I would love to be able to change the rebill date in a workflow. The primary functionality for me would be for an invisible funnel, were they get access to an event for free, but are billed for the event 72 hours after the event. Right now the rebill date (or the bill date after a free trial) is set to a number of days. So I either have to update the product daily OR I have to change the bill date to 72 hours after the event. It would be great if I could do that in a workflow
