Negative Filters (e.g. Labels)

In order to help me filter things into collections and labels, it'd be great if I could make a filter for movies that are not in a label/collection so that I can review that list and add anything that I think should be added.

 

For instance, if I made a 'family' label, I'd like to be able to see all the movies not labeled 'family' and fix any that aren't.

I agree, very useful
