Adding New Items in Purchase Orders

In our business we are regularly receiving new stock items to sell all of which need to be added to the DB. When receiving stock from an invoice in our current POS (MYOB Retail Manager) if the item was not in the DB then RM would offer to open the New Stock/item window to enter the details (i.e. Description, cost, retail, supplier etc) then add it the the receive window. We have RMS up and running but it seems that if a ILC is entered in Quick Scan that is not in the DB there is no quick seemless way of entering the item details and then have it automaticly appear in the Purchase Order. It seems one needs to goto items & New or New Item Wizard to enter details then return to the PO window and enter the new item's code again. Seems like too many mouse clicks/Key strokes. Is there a better way? Is there a key stroke to take the place of a MouseOver & D/Click
