Min/Max Quantities for WooCommerce

to have an option to override the rules on certain products – let me explain – currently i have a min order of 30 cards, which is fine for individual cards, but I also have a single product of ’50 pack of cards’ – but it is counted as 1 in the cart and not 50 – so if you add one 50 pack and 5 individual cards – it is only 6 in the cart (5 individ cards + 1x 50 pack) instead of 55… and then the min error comes up…
