Automate Return to Supplier after Return to Receiving? (Dropship)

Hello;

We are a dropship operator, R12.1.2.  Booked Sales Orders generate Purchase Orders out to our vendors, who in turn ship the goods to the end customer.  We receive and process the vendor's Advance Shipping Notices via EDI transmission, which performs the P.O. Receiving.

When we do that, the steps of "Receive" and "Deliver" happen all at once, for the item/quantity in question.  Works great...

When we have a merchandise return to perform, we create a Return Sales Order, and then go on to manually perform "Return To Receiving", followed by "Return to Supplier-Vendor".  Those 2 steps are separate from each other, and are manual steps, and thus subject to human error; whether a simple mistake, lack of attention to detail, etc. -- this 2-step *manual* process allows for seriously messy mistakes to be created unintentionally in the process, if both manual steps aren't 100% correct and timely.
