Currently, the platform only allows coupon codes to be added at the product level. However, if a product has multiple variants and we want to apply different discounts to each variant, this is not possible. We cannot add a coupon per variant, and we also cannot duplicate coupons in case we want to create individual products for each variant.
This feature would be extremely useful for customizing promotions and discounts, especially in cases where there are products with multiple variants that require different pricing or discount strategies.
