More options for sorting cast as actors

Instead of having to use the reenactment keyword for titles that don't feature reenactments, I would like to see other ways to categorize credits as acting credits rather than Self.

For example, most talk-shows have non-fiction as a keyword, which sorts all their credits as Self. This includes Da Ali G Show, The Dame Edna Experience and other shows with actors appearing in character. We have seen in the past that even deleting the non-fiction keyword is not enough to change how the credits are sorted:  only adding reenactment on the episode level helped.

Preferably, even a Dame Edna appearance on an otherwise non-fiction show should be sorted as acting.

Since all Self credits should include Self in the character name, I wonder if it would eventually be possible to stop sorting all documentary and non-fiction credits as Self.
