Smart Coupons

We have a real world standard scenario. We run many Festivals and at the GATE they purchase 3 adult tickets a child ticket and a senior ticket.
They have two $3 off Subway coupons that can only be used on adult GATE tickets.
I don’t see how to configure this extension to apply based on how many coupons they have for that one product. It either applies to all products or only one.

Ideally, we would scan a barcord on the coupon and woocommerce would apply on products the coupon is good for… not all products.
