Adding 2 Equipment numbers to a WO

Hello,

We have a requirement to have 2 equipment Numbers be attached to a Regular Work Order (non MFG)

Business Scenario:

Operational Work Orders (WO type of 9) are created to capture employee labor costs that relate to pushing dirt around a yard with pieces of equipment (dozers) as an example.

We set up these WOs with a VIRTUAL PIECE of Equipment in the WO to capture the different type of "operation" occurring and now we need to somehow identify the piece of equipment used by the operator.

Any thoughts would be appreciated.

Thanks
