Prep Gear From Different Warehouse

My company has one main warehouse and two satellite locations that are much, much smaller.  When we do shows at those locations, we almost always prep the whole show from the main warehouse.  Those locations have no staff.

Currently, when a Quote is generated from one of those locations, we have to create a TO to transfer the gear.  With no real staff to receive and fill it to the job, availability gets screwy. It would be MUCH easier if we could generate a Quote from that location and choose to use the Main Warehouse for the gear.  

Is there a way to do this?
