Coupon applies to all products in an order, not just the order total

We c have a coupon code set up. It is d for All Products. When an order is placed, it deducts for each product in the order. We need the coupon to only apply to the total order, not each line item in the order.

We need another selection in the coupon drop down box. Right now the selections are:
All Products
Product Category
Product

Please add "Order" to this list so the coupon applies to the entire order, not each line item. This is killing us a promotion we are doing that we cannot change with the vendor.

Thank you.
