I don't have this particular item, but it does seem looking in the iTunes Store that it comprises some 250 tracks, 15 iTunes LPs and 15 videos. It would seem that all tracks are listed with the same box set artwork under the album name of The Beatles Box Set, rather than being presented as the individual albums that comprise the set....
I haven't tried this with a box set that includes iTunes LPs, but I have edited metadata for individual albums with iTunes LPs without breaking them.
I am replying to you so I can include the above. The OP can accomplish what he wants, I am pretty sure, but it will be very time consuming. He will have to decide whether the time is worth it or not. I have done it for a much smaller set, 2 albums with 37 tracks and it took time. Doing this for 15 albums with 250 tracks will take many hours if not days. I don't have this particular set either but the problems I see are: 1) based on what you said above, all tracks are under a single Album Name, The Beatles Box Set and 2) how the individual track numbers show up in iTunes. IF the tracks are all under one album name with numbers 1, 2, 3, .... 249, 250, he would have to edit each and every track to change not only the Album Name (and Artwork if he wishes) but also the track number, a royal pain.
I'll offer an example. Please take a look at this Screenshot:

I have a 2 CD set called Vivaldi: La Stravaganza. CD #1 contains 18 tracks under the album name "Vivaldi: La Stravaganza" and with track numbers 1 through 18. CD #2 contains 19 tracks under the same album name with track numbers 1 through 19. After I ripped both CDs with iTunes they showed up (as expected) under one album but the tracks were 1,1,2,2,3,3,....18,18,19. No way to play in that order as it ruins the flow of music. Obviously when playing each CD with a CD player this was a non-issue but trying to play this 2 CD set with my iPhone was a non-starter. I really like these CDs so I had to edit each track, all 37 of them. Using Get Info I edited the album name of each CD #1 track as coming from a new album "Vivaldi: La Stravaganza 1" and all tracks of CD #2 from new album "Vivaldi: La Stravaganza 2". Then bingo, 2 albums appeared in iTunes under those album names with the right tracks in the proper order. I left the Artwork the same as I can distinguish the albums by their new names.
For the OP, if all 250 tracks are currently under the same Album Name, they will appear as one album in iTunes and also in an iPhone. To do what he wants he would have to go into each of the 250 tracks and change the Album Names. He would have to select the tracks that fall under the first album and change the album name as he wishes, "I want to hold your Hand" or "I want to kill you for making me do this", and then edit the track numbers, let's say 1 through 15, so they play in the proper order (this may not be necessary if he is willing to live with album #2 having track numbers 16 through 30, etc.) He would then have to select the tracks for the second album and do the same and on an on for 15 albums.
Maybe you have a magical fast way of doing this... 🙂
Here is another example but going the other way around.

There is no such album. I ripped 18 tracks from various CDs, most named differently and with their own artwork. The tracks showed up as expected under their original album names. I then edited the album name of each track to "Celia Cruz Selections" and the album artwork to one I liked. After doing that for all tracks, all albums consolidated into one. But I also had to change the track number of each track so they would play in the order I wanted.
I have synced both of these albums (and others done the same way) to my iPhone and iPad and they show up as they do in iTunes, 2 albums for the Vivaldi and one album for the Celia Cruz.
All I can say to the OP is good luck and sorry. Maybe tt2 has a faster better way... 🙂
