it is annoying that it can't remember it by series. Perhaps for a normal series I don't want captions but for a foreign language one I do. Perhaps for a foreign language that I'm good at I don't want it, but for others I do. Perhaps for a foreign language that I'm learning, I want it in that foreign language (ala english for english content) but dont want it for others.

Global "works", but remembering by series would be so much better.
