How to delete WO reservations when the component has been picked to an intermediate subimnventory ?

Summary:

We pick our WO components from our main warehouse to an intermediate 'Mfg Stage' subinventory. We then issue the components later to the WO. I am finding that I am not able to delete the item reservation once the pick has been completed to the Mfg Stage Subinventory. The same problem is even more if specific serial numbers of a component were pick confirmed and now sitting in Mfg Stage and now we want to remove that reservation and send some other serial number.
