Add Cash Discount Price to BTO Config Pages

Is there a way to add in a real-time discounted price on the configuration page, such as a cash discount?

Basically, on the BTO configuration pages... where it has base price, customization prices and total price... I want another line that has a price that has a discount deducted from the total price.  For instance:

Default Price: $2499
Customizations: $1000
Total: $3499
Cash Discount Price: $3299

Where the cash discount price would be calculated as a percentage off of the total price.

Hi JWL,
   At the moment ProductCart doesn't support this.
ProductCart already support many marketing features including different discounts / customer pricing categories & reward points etc.
Is this for particular customers or all?
Customer pricing categories is the closest match - And it's possible, with a small piece of custom code to automatically assign new customers to a pricing category, the downside to that approach is that customers have to register/login to see the reduced prices - Although you could use that as a way of getting customers to register using some text such as "Register now for instant special offers" :-)
The code would still need customizing to show the savings on the individual BTO Items instead of just the reduced price.  
Perhaps post a request for this as a V4 enhancement on the forum.
