Is there currently any option in the app market to do variable or percentage based price modifiers? If not there should be.
Use case: A Restaurant I work with has 300 different types of liquors.
A bourbon can cost $10. To make it as an old fashioned would be $5, so half the cost of the bourbon. Another liquor could be $5 and an old fashioned would be $2.50. So instead of making 300 different modifier groups, just make one modifier group and have it go based off a percentage of the item price.
As it is looking now we are going to have to do 300 different types of modifiers.
