Returnables packaging

Hello All,

Is it possible to use a returnable packaging material as a packing material and still be able to trace the returnable material against the customer. Like say i sell milk in crates; crates is the returnable packaging material, Can i create a sales order for only milk and using the pack function in delivery, pack milk into crates, and still be able to trace stock of the returnables using mb58?

If not, what is the best approachh?
