Can I create a new field in Quotes under product details?

We use the list price, then apply a discount.  We need to show the product's price AFTER the discount has been applied.  Is there any way to create a field to be shown on the quote template that will be the result of the list price minus the discount?  (not the line total, but the per piece price after discount).
