MP: Coupon codes and Automatic Discounts based on qty

Is it possible to have a discount automatically applied to the cart if a certain quantity of an item is purchased?

See a product here:

We need the ability for someone to be able to get a quantity discount on products even if they are not the same design. So if you were to purchase 5 notecards but all in different designs/photos, you would still get the qty discount.

Also, is there an ETA on product-specific coupon codes?
