Currently when adding a guest cast, autofill will automatically enter the character for an actor (if actor is playing a single character). However, that doesn't work for the main cast. I.e. when actor is playing some character as guest star in the first season, and than promoted to the main cast in the second season (as the same character), when you add this actor to the main cast the character is not autofilled, so you have to enter it manually.
Or maybe it's it a bug or done intentionally?
