Return to Supplier for Credit Only - process without subinventory

Summary:

We would like to create a Return to Supplier for Credit Only (Redwood features), but we will not be bringing the inventory back in house, thus want to process this without a subinventory. Is it possible?

Content (please ensure you mask any confidential information):

We are looking to use a 3rd party application to enable our customers to create returns on sales orders placed in our system.

That application will interface and create RMA orders in Order Management.

For some of those returns, they will be products that were filled via dropship. Customer create return, print shipping label and pack slip, and send directly to vendor.
