Linking Drop Ship PO Line to SO Line in Import Scenario in the Sales Order screen.

I am working on a business event and import scenario where I need to add a line item from the Drop Ship Purchase Order to the corresponding Drop Ship Sales Order. Additionally, I am trying to establish a link between the Sales Order Line (SOLine) and the Purchase Order Line (POLine) through the import scenario. Is there an option to map import scenario for the Purchasing detail pop-up window and select the respective PO to create the link.
