Ah right. That makes a lot of sense. It might still be nice to have the
series+episode number used for the subtitle when no other subtitle

Another thing I'd like to be able to do is make use of series and 
episode in user jobs. Are there any equivalents to %TITLE% and
%SUBTITLE% already, or would it make sense to have them?
