I was surprised to see that "Apply discount only once" checkbox on discounts only works with amounts. Is there a reason for this?
Most of our customers use percentages and they reported it as a bug. In my mind there is no reason for this to be a restraint to amount, as it could easily be with offered Products as well.
This became an issue because this customer using 9.4.17 (we are planning to upgrade to at least 9.5 very soon), used to have the Sales Discount with a custom discount called "Buy X Get Y", and we're trying to move him away from that, and this is currently the once constraint. Is this an easy change that can be done?
