Is possible to defined consignment line in the purchase order and not in the agreement ?

The customer needs to decide whether a purchase order falls under consigned inventory or not at a stage after the agreement is created.

Oracle gives the option at the agreement definition stage to check the “consignment line” box. After checking it, created an order linked to the agreement, in the schedules the “invoice match option” field is automatically populated with the “consumption advice” option. If the “consignment line” box is unchecked oracle offers a choice of invoice match option “order” or “receipt”.

We would like to be able to have the option to select the “consumption advice” option even if the agreement line is not a consignment line avoiding the work around of creating two agreement lines for each item (one consignment and one not).
