Filter by multiple Collections in Browser

[anachrophobia]

I'd like to filter by / select multiple collections in the Ableton Browser. As of now, I can enter multiple keywords in the search panel which get connected by "AND", but I can select only one element from the browser panel to the left to tell the browser where / in what collection to search.

Now what I'd like to do is select multiple collections, to see only the items that are in all of the selected collections. If I wanted to, I could then limit the search further with keywords. For example if I had 2 collections, one called "Drums", one called "Loops", I'd be able to select both to get all looped drums, maybe alongside with the keyword "hats".

I think this would provide a major improvement for the collections feature and the search functionality.
