It would be very helpful to have an exclusion option within the coupons. So if I have a particular one-time product I don't want a coupon to apply for I can just exclude it. Currently the only way to make this happen is to add every single one-time product to the coupon which is time consuming. You then have to make sure to go back and add any new one-time products to the coupon if you add any in the future. Excluding a product(s) would be much easier.
