Show discounted amount on sales order / invoice against MRP when using Price List

Zoho has this great feature of having different Price Lists. The only thing missing perhaps is that MRP isn't shown when a price list is selected and discounted amount isn't shown on Sales Order / Invoice. 

This simple feature could be a great tool for psychological win when a customer makes a purchase. Since, a discount is being provided but currently there isn't a way to highlight it, unless I am not aware of such option.
