You’re right that this isn’t possible at the moment. I see where you’re coming from, but I wonder if there is a better solution for the problem? Would it be better to have a setting more like Print one label for every X cases of the same smallpack product if more than X on a single delivery.
For example, you could configure as Print one label for every 10 cases of the same smallpack product if more than 10 on a single delivery and:
If someone orders 5 cases, you would get 5 labels.
If someone orders 10 cases, you would get 1 labels.
If someone orders 15 cases, you would get 2 labels.
If someone orders 20 cases, you would get 2 labels.
If someone orders 25 cases, you would get 3 labels.
Would this work for you? Would this be better than toggling on/off on a per-customer basis?
