Restaurants - sum total modifiers (>1 for each modified select)

Items in restaurants let you select modifiers in a binary 1/0 option. Would be better to have scale options, i.e. select modified one equal to 6, modifier two equal to 0, modifier three equal to 2 (sum total of 8).

*Key for restaurants where items are a selection from a basket (i.e. pick wing flavours for 10 wings; user picks 5 of one flavour, 4 of another, etc.)
*Feature does not currently exist as modifiers are binary off/on
