Hi there, thanks for your review! There actually is a way to create variant exclusive codes. All you have to do is create the discount in our app (where you can't isolate variants) and then after the discount set is created, look up the discount under Shopify>Discounts and change the product conditions in there to include/exclude certain variants. I hope that makes sense, if you have more questions please don't hesitate to reach out to our support team!
