In Adagio Inventory, is it possible to create codes for kits or for a combination of products already on our system?

For example, we have a code set up for Item A at $10 and a code set up for Item B at $10. Our promotion this month is, if you buy Item A & Item B together we offer a $5 discount. Could we set up a new code called Item C that would take the inventory and costing out of Item A & B and then sell it for the price of Item C ($15)?
