Ability to specify start date for Coupons

[thunsinger]

While having an automatic end date and time for coupons is available, it would be very helpful to be able to set the "start" date and time, as well. This would allow advanced set-up of coupons, based on marketing efforts. During our holiday rush, we simply do not have time to create the couon and go through the slow process of selecting products if we are promoting a specific brand or item type.
