Cost Profile Transaction Costing Rules

Summary:

Our client has a requirement to use perpetual average costing and wants to transact RMA receipts with using a specfic cost which is neither the 'Average Cost at Sales Order Issue' for Referenced RMAs nor the 'Existing Item Cost' or 'Price on RMA Order' which are the available options in the Cost Profile Transaction Costing Rules. Does anyone know if one can pass a value to use for the cost through the receiving transactions interface through which RMAs returns are processed? This would be akin to setting the 'Use Current Cost' setting to 'No' on the 'Miscellaneous Transaction'
