Hi. I want to apply a discount to all products based on either the total number of products purchased in a category, or at least all product variants. If I give a discount for buying 5 or more products, and they select a different color for each (product variant), they should still get the discount. Is there a way to do this? If not, it would be a great add in a future release, it could just be a checkbox next to MOQ saying "Count all products in category".
