Grab & Retrieve players (logic)

Assuming this odd mechanic isn't thought of already, it'd be cool if you could play CTF using a player as the flag. Basically I would like Quidditch to be possible where a player can be the snitch.
You can do that by making the capture locations trigger when the snitch which is on it's own team gets in the corresponding zone and then give credit to the team whose zone was triggered.
