Process multiple tips at once

Recently I tipped someone $1, only to later find out that they only got 67 cents of that because of Stripe's exorbitant processing fees. I know they're probably the best y'all can do, but it still gets my goat.

Would it be possible to "save" a tip in a cart for a certain amount of time, 24 hours maybe? During which time, more tips could be added to the cart, and then they could all be checked out at the same time to minimize the fees charged. More money for the recipients, more money for Imzy (from people who choose to donate to Imzy). Everyone wins! Except Stripe.
