Customize Amount of Modifiers Allowed

[#1]

Right now if you have modifiers it's either limited to 1 or unlimited modifiers. Can we have a box to specify how many modifiers are allowed? That way I have have a limit of 1,2,3,4,5...etc modifiers. For example if we have a Single 3 topping pizza, we want to limit the free modifiers to 3. Right now it's either 1 or unlimited.
