Would like to be able to add parts kits from another RT and use that RT's stock

In multi rooftop dealerships, when you add a part kit to a part sale or work order, the stock will always come from the location on the transaction. Would like the stock to bill out from the location set up on the parts kit. So for example, if 'PK1' is set up for Oil and Filter for RT-A, but is billed out on a RT-B work order, would like the stock to come from RT-A
