Is there a way to automatically add early payment discount on customer payment receipts? I currently go on Customers -> Receive Payments . Then for every invoice, I have to individually select the invoice number, hit "Discounts and Credits" and hit OK to have quickbooks calculate it. Is there anyway, to automatically do this step when I just click the arrow key? 

The issue I have is that I process about 20 invoices at a time and it's repetitive. Unfortunately, I have some invoices that are  % 10, Net 30 and some that are Net 30 for this particular client.

Any input to reduce these steps are greatly appreciated.
