Deals based on products do not use SKU - please add SKU to the product display field

When setting up a deal based on "add products" the products can be searched for using their SKU but when added to the deal the display to the right only shows description and not the SKU.  This makes future management difficult as you have to be able to identify the SKU from the description i.e. you need to have good knowledge of the products.  It would be much better if the SKU could be displayed in addition (or instead of) so that products can be easily identified.
