Need to enter Mac Address as well as serial number

Hi

We have a requirement where we need to track the Mac Address for IT equipment as well as Serial number of the items.

In Inventory module we have a field for Lot control & Serial control ,we need another field where we can enter the Mac address/number for the IT equipment which we will be receiving in

Inventory module and sell using Order Management module.

Is there a field for that ?

A DFF will not help as we should be able to track the items by Mac address in the same way we track them with the serial number .
