I wonder if some weird kind of aggregation could go on.

At the end of the month, I'm told to donate my entire $10 to some obscure tool I've never even heard of.

The system did all of the tracking, across all users, and then figured out how to assign users like me to projects, such that I'm only donating once or twice ($6 to this project, and $4 to that project.)

The system I propose does all of the counting, all of the aggregating, matching intended donations to the recipients, and then encourages me to do my actual gifting...

Seems possible, but weird. Or maybe we need to set up a non-profit to do all this money laundering^W^W donating.
