Putting movies on other lists straight from the watchlist

I want to categorize movies from my watchlist in to other lists so i would know which movies to pick out when i am in a mood for example foreign films. Problem is that you need to first enter the page of a movie and than choose which list you want to put it in. My idea as the titles suggests is for making it possible to add a feature that allows you to put movies on other lists while you're still on watchlist tab, not a big change but it will ease up sorting movies especially for people who have a lot of them and going in to each of their tab would take a lot of time.
