Distinguish between songs I've ripped from CDs I own and music from my subscription

JSAbrahamson submitted the following back in April 2023 and since they articulate my same exact question more clearly than I could I resubmit their question. There is a reply but it doesn't answer the question.

History: I have ripped 2000+ CDs worth of music, that I've collected over the last 40 years, to my Library in Apple Music. I also have an Apple Music subscription and add music to my library via the Download to Library/Playlist option.

Question: Using the Songs List view in the library, how do/can I distinguish between what I've added via ripping and what I've downloaded, but not yet purchased to own?

Point: I'd like to sort my Songs List by what is in my Apple Music Library and what I own and on my hard drive. That would allow me to more quickly go through what I don't own and purchase what I want.

If there is not way to do this via Apple Music, there should be. I like to listen to/explore a variety of music genres - some of which I will never remember later. I'd like to occasionally evaluate the music I've "downloaded" and "purchase" what I want so it is in a more permanent library. Under Apple Music, if you unsubscribe you lose access to what you've downloaded to your library. Life can get hectic; oftentimes, a song or group doesn't resonate with me after just a few plays, but once I gain an appreciation for them I'd like to support them by purchasing their music.

The question may have gotten lost, but I'd appreciate a response if you have an answer. If there is no answer, maybe Apple can work on providing an option if enough people agree. Thanks in advance.
