Order Level Adjustments With Split lines for backorders

When an Order Level Adjustment is Applied to the Sales Order, a New Line is created that has the Extended Amount equal to the Discount Percent multiplied by the Order Total Amount.

If I am Hard Committing in Sales Order Entry and I alllow Partial Shipments, then a new Sales Order Detail line might have been created for the Quantity Backordered.  

The Order Reprice calculates the Total Sales Discounts for all Sales Order Detail lines including the backordered lines.

Is there anyway to split the Sales Discount so that the only Sales Discount Amount that goes on the Invoice is the Sales Discount Amount for the Shipped line quantities?
