Is there a way to populate the Destination Subinventory on an Approved Requisition Line?

We are still running 11.5.10.2 and using Spares Management to create Internal Repairs.  This process creates both Approved Internal Reqs and Booked Internal Orders but the destination subinventory is blank on the reqs and there is no option to populate the value.  I'm looking for a way to populate the destination subinventory on these requisitions so we can specify a repair subinventory.

Any way to do this?

Thanks

Bill
