Add the ability to track stock quantity by individual modifiers under a modifier group. Currently you are only able to track the total quantity of an item. This is not helpful when you use modifiers for sizes of shirts or colors of hats. For example, if I sell a short sleeve shirt and we have 20 total shirts it would be helpful to know that I sold a Medium and my count of Mediums is 1 remaining because the sale. The current functionality just says I now have 19 shirts remaining. This would allow a more efficient process to understand inventory quantities. The other option is to not use modifiers and have 5x as many options on the screen to choose from which defeats the purpose of using modifiers.
