Ability to see if ANYONE from a certain server shares a different mutual server

I'm aware you can check a person to see their mutual servers, but I don't want to check each individual person to see if we share servers. It would be awesome if you can check with a couple clicks if anyone in a certain server is ALSO in a different server. For example, let's say you are in the A server and also the B server, you could click a button and select to see if anyone from A server is in B as well. It would be a fun conversation starter and a nice way to make friends.
