RSSP One-Time addresses (drop-ships) /we want to continue using unstructured addresses

Summary:

How to set RSSP to use unstructured one-time delivery addresses

Content (please ensure you mask any confidential information):

We are testing out RSSP. In classic SSP, we use unstructured one-time delivery addresses & these populate onto the PO line as an attachment when processed.

RSSP out of the box is showing structured address fields.

• The Capture One-Time Delivery Address in Structured Fields on Requisitions feature isn't enabled.
• The Allow One-Time Address option is selected for the requisitioning business unit.

We'd like to continue using unstructured one-time addresses while switching to RSSP. How do I configure this seeing as it is already configured properly when we use classic SSP?
