How to get the real layer cost from RMA transaction ?

I have the following issue. Till the moment we sell the item, every layer has it's own cost, but when we receive it back from RMA transaction, the system makes new layer, with average cost for the received items. So for example we are selling 2 PCS from item A with Layer Cost 1 = 10USD(1st pc) and Layer Cost 2 = 20USD(2nd pc).
