Quantity Discounts & Pricing for WooCommerce

Hi, I sell variable products, variations are created based on two attributes: Size (e.g. M, L, XL…), and Packing. For Packing I use “a pack” and “a piece”. I’d like to offer discounts for pieces, but not for packs. I could easily accomplish it would there be an option to include another condition in the rule, in this case “attribute Packing equals to ‘a piece'”. Would you consider adding such a feature?
