e.g. the back cover on https://musicbrainz.org/release/9b6f843d-43c8-463e-a050-46e62be50daf/cover-art shows

"(p)1977 Original sound recording ... (p)1987 digital remastering"

I think it would be useful to have a way to distinguish those relationships with attributes rather than having "(p)1977,1987" currently, for example:

• original mastering
• analog remastering
• digital remastering

or just two choices "nothing" or "remastering" would be enough
