Can ASL error message be triggered when entering items, instead of after submitting the full PO/BPA?

Summary:

To prevent users from wasting time when creating a PO or BPA with items subject to ASL restrictions, we would like the error message 'The supplier isn't approved for the ordered item or category' to be triggered immediately when the item is entered in the PO/BPA line, rather than only after the entire order is completed and submitted.
