Flat price model on pricebooks does not appear on quotes

We are using Price books with Flat Discounts price model.
When creating a quote with quantities which should apply for some discount, then the total price includes the discount, but the price per unit that is shown is still the original price, and there is no indication for any discount.
So you get a line like:

Product Name ---- Unit price: $100 ---- Quantity: 1000 ---- Total: $72,000

$72,000 is the price after the volume discount, but for the customer who gets this quote it will just look like wrong calculation - 100x1000=72000...

Please advise how to show either the discount or change the price per unit.
