Do you want a function that do this for you (I mean create folders and move movie files automatically) OR you have already moved files and you want that XMM detect this change?
either function would be fine. so far i haven't made the change because i'm afraid i'll have to make a complete reimport (over 2500 movies). since your asking, the possibilty to create a folder based on the movie title in the database + year of realase and then move the file(s) to that folder would be great of course.
