Hey. Occasionally I ingest movies that are Not Rated (either because they are actually not rated, or because Plex doesn't grab their metadata properly). I'd like to use Common Sense Media to fill in ratings for these movies. It looks like mass_content_rating_update: mdb_commonsense is likely to work. But I'd like to do this without affecting the ratings for any other movie.
So far I've mostly used PMM for syncing external lists as collections, I've never actually used it for metadata management. Any advice for how I might do this? Thanks!
