Adding a person to Favorites... Which favorites?

Let's say I add a music artist to my Favorites, but he or she is added to the Favorite Actors & Actresses, not to Favorite Music Artists, probably because he or she appeared in some movies or TV shows. For instance, Sade, the singer, Florence and the Machine, James Taylor, and others.

My "feature request" would be that I can specify which Favorite list I want a person to be added to. Possibly more than one Favorite list, if she or he is a favorite Music artist and a favorite Actor or Actress of mine!

Same issue for an Actor who is a film-maker or an author too. For instance, I would like to add Clint Eastwood to my Favorite Directors, but he is only added to the Favorite Actors list.
