Bundle Priced Individually as a Dollar Amount

Currently, Bundled items, when “Priced Individually” can only be output with a % discount. There are many instances where a simple $ discount would be easier to input. For instance, a $49 item being sold within a bundle at $29 needs to be inputed as Discount % 40.81632653. It would be faster to have a Discount $ option and simply enter $20.
