Invoice Price Variance combination account

Hi,

In the Inventory Organization definition (Other Accounts) tab is setup the "Invoice Price Variance" combination account.

When a match purchase order is entered and the unit price is changed at Match Invoice form level, the differece generated is charged to the combination account defined for Invoice Price Variance.

My customer has the requirement to charge the variance to the PO charge account (the material subinventory account or the expense combination account setup in the Item that is purchased.

Is there any way to do that? Or the intended functionallity only allows to charge the variance to the "Invoice Price Variance" combination account setup in the Inventory Organization definition?
