Sometimes I receive payment for one task and I need to pay for a service or product with another credit card. Say I have $1500 paypal credit from one of my businesses, and want to pay a $500 charge from a certain credit card. I am not able to do that without first withdrawing the money. It's beyond annoying, just let me pay with the funding source I want.
