Pro-Sites Feature Request - Charge Subscriber immediately when payment submitted while on trial

Currently, when someone on trial decides to pay, the payment does not process until the end of their trial subscription. This confuses many customers, who expect that when they put their payment info in, that they will be charged that day. It also delays our receipt of this revenue.

Is there a way to complete the payment at the time of the transaction? Is there a workaround or a way to add this feature?
