Gift Certificates - Include In Discount Subtotal

Is there a setting to include the value of a gift certificate purchase as part of a subtotal in the calculation of discounts?


$40 gift certificate

$20 in physical products

A "free shipping" discount applies to carts with > $30 in value.

So in this case a customer has to pay shipping for the $20 in products even though they are spending more than $30.

So we would like to include the value of the gift certificate as part of the subtotal for the discount to apply.
