Hi there.
Please consider adding an option on to your item modifiers where you can select a quantity per modifier.
for example: i run a donut shop, we offer half dozens and full dozens of assorted donuts, we let our customers choose their flavours. the modifiers allow us to list all of our flavours, under each box, but it doesn't give an option for how many of each donut they would like, unless i listed each flavour of donut 6 times per donut, which is unrealistic. If each modifier had an option for a number count beside it that would fix my whole problem. if they order a box of 12 but wanted 8 of one flavour 2 of another and then 2 more individual flavours, having a drop down ranging from the 1-12 under my dozen box would be great.
