Already here with various users giving input: https://kisskh.at/discussions/suggestions/17477-in-filter-dont-list-drama-or-movie-which-is-already-in-my-list
Be sure to read the sticky post with all the existing suggestions. :) This thread itself will probably disappear, hopefully after you see this!
**edit: and go throw your votes and thoughts on the one that already exists so admins know more and more of us want this feature! I desperately want this filter just like you. (When I came it was already a suggestion thread, so I gave it 3 votes and it has, in the time since, bumped from medium to high priority because people keep upvoting.) 😊
