Is there any way to change the default behaviour of the Active Playlists generated by Mezzmo without having to delete them all and recreate each one individually using Smart Playlists?

Example: Active Playlist - Artist. Okay, the first thing is to delete the Genre subtag so I get a single-level sort. Easy enough. However, I can't find a setting which would force the playlist to list sort by Artist instead of by Artist(s).

For instance, take the two music video files:
  • Piano Man (Title)
    • Billy Joel (Artist)
  • Baby Grand (Title)
    • Billy Joel (Artist)
    • Ray Charles (Artist)

What I would expect for an Artist active playlist would be:
  • Billy Joel
    • Baby Grand
    • Piano Man
  • Ray Charles
    • Baby Grand

What I actually get is something not very user friendly:
  • Billy Joel
    • Piano Man
  • Billy Joel/Ray Charles
    • Baby Grand


So - is there any way of getting the Active Playlists to behave like the first example without having to discard them entirely?
