Hello, I would like to make a pricelist where the change is applied if the quantity is equal or larger than X.

For example, suppose A and B are items in the same category F and the price list includes a 5% discount for a quantity of 10 or larger and an extra 5% discount if the quantity is 20 or larger.

I set a rule that applies for category F. What happens if a client buys 15 units of A and 5 items of B?

I would like that 10% discount is applied to the whole sale, since the promotion applies to both items in the same category in unison. Instead, POS is setting a 5% discount to item A and no discount to item B. Is there a way to fix this?
