How to access Release Group relationships from Picard?

Hello,

I would like to be able to access the release-group relationship “tribute” for this release-group https://musicbrainz.org/release-group/903ee17d-b5f3-3df6-973a-c435b170d7da in Picard so I can tag it with albumartist:Iron Maiden rather than Various Artists as this info would be much more useful for my file structure.

How can I do this using Picard?

All I can suggest is to tweak the title of this thread.
Perhaps try: How to use a release-group relationship in Picard?

I don’t think it’s possible without a plugin.
