how to create a watch later list for netflix app?

Til now we can only: add to list, like or dislike a video. Adding to a list is not really useful because netflix app wont hide items we have already watched, so we lose a lot of time browsing a long list of things we have already watched, almost pointless, I dont do it anymore... Like or dislike makes no difference either, doesnt help (each of) us, wont hide, not even mark/highlight, the item either... Do you know any tricks?
