You can do that. It's called a restricted donation. If you make a donation with a cover letter or a check memoizing a specific purpose and the nonprofit accepts it, then by law they're legally obligated to follow through and use that money for that purpose. With bugs it's probably easier because you can just write the bug ID on the check.

MZLA Technologies, the organization that these donations go to, is not a non-profit.

There are also a couple of bug bounty websites out there for exactly this kind of thing: you and others throw some money into the pot for fixing a given bug or implementing some feature, and coders can claim that bounty once they've written the code.

I've seen a few of these sites over the years but I can't remember the name of any RN. Search engines are your friend.
