Example: I own all the Beach Boy songs from Pet Sounds. I don’t own the Pet Sounds album. I want to create an album named Pet Sounds and copy track by track all the songs from my greatest hits albums into the newly created album.
thx.

It seems to me that the best you can do (at least with only an iOS device) is create a playlist called "Pet Sounds" and copy the songs to that playlist.
Create and share Apple Music playlists - Apple Support
On a computer you could do the same, then burn that playlist to a CD and then import back into your computer. But in the import process you may have to manually rename the CD, album artwork, and each song. The only way to know for sure is to try it. If you want to go that route, reply back and I can point you to the instructions if you don't know how.
Create my own album from songs I own.
