Create "rules" for modifiers when the quantity is increased. Ex- the "market spread" on our menu requires 3 seasonal toppers/sides to be selected. For each order of the same market spread you should only be able to selected the same toppers as the orginal. If the market spread is rung under as 3x quantity there should be a requirement of 9x toppers, but only three different ones should be selected at 3x each.
