Being ablo to add aditional charges to customers

Before moving to Stripe Express we were able to create and charge aditional services to customer since their billing profile was created after they had purchased. you were able to charge their card directly instead of sending invoice. Now in stripe express we cant manage individual transactions. Will be nice to be able to create a custom charge on customer profile. For example We use the bags charge in reverse. We believe having the credit bag charge up front harms the sale. We do it in reverse. We let know people that if they keep the bag they are charged a deposit instead of charging up front. Keeps a healthier relationship
