Carrier Charge backs via CSV

It would be great if there was a way to upload adjustments in bulk via CSV for shipping charges. Since the carriers invoices do not reference our shipping number possibly it could be tied to the shipments tracking number. File would just call for Tracking number, cost, list price, comment. It would be great if these could be added as a billing line on the actual order similar to if we go into the order scroll to the bottom and select adjustment. This allows the client to access this information once the statement is created.
