Another Artist Confusion

The female jazz group Lioness (on Posi-tone Records) gets the picture and write-up for some Toronto group of the same name which doesn’t play anything close to jazz and isn’t all female. It’s probably too much to expect this to be fixed by roon or its metadata provider, so how can users edit these mix-ups to get it right for themselves? I know how to change the picture and the tags, but what about the description?
