I’d like to be able to filter sharing via label, not just adding stuff. For example, if I have something labeled “parents” on my kid’s account I could add the label “!parents” and it would ignore items with that label.
There is a previous request for this. Best thing to do is to ‘like’ the first message in that thread in order to vote for it.
