It would be very useful to have the ability to link specific Discounts to specific Products or Product Categories. When offering standalone products and subscriptions, it's imperative to offer a discount on a subscription that someone can't turn around and use on a standalone product. For example, it would be useful to give a coupon for, say, $5 off a specific widget that prevents someone from using it on anything they want, especially products that cost less than $5.

Thanks!
