Add discounts used in triggers

It would be great to add discount used in the custom triggers so we can adjust the upsell offer accordingly. If the customer already ordered with a discount we’d want to be able to show a different offer than to those who have not used a discount, yet. For instance, we offer military discounts. If the upsell offer has a lower discount than the military discount on their order, they’re not likely to take the offer since they can buy it at a lower cost.
