Ability to filter out / hide certain collections

We would love to see an option where I can have a collection shared with me, but then not see items from that collection in my day to day usage - confusing to know which item to select (my own, or the one shared with me). Could there be a way to show/hide each collection? If I have an item in a hidden collection that matches the current domain, perhaps with a note saying ‘more items available in a hidden collection’.
