Maybe you can use quota arrangement - creat an inbound quota arrangement with the two PDSes. For the one you want to use, assign 100% quota, and the one you don't want to use, assign 0 quota. Quota arrangement is the top consideration during source determination. So you can change quota arrangement to control which PDS heuristic should use. If you want the heuristic to pop up the SOS selection screen as you create order manually in planning book, I think it could not be achieved with SAP standard delivered functionality.
