I like to create one or more action to do this:
Field ARTIST: Name 1\\Name 2\\Name 3 (separated by\\)
Field ARTIST: Name 1
Field SOLOISTS: Name 2\\Name 3
or another case where Name 2 should just be deleted.
I tried several combinations with guess values %artist% and guessing pattern $meta(artist,n) but for some reason it doesn't work so i do something wrong.
