Use negative values in Quick Add

Kmcmurphy

I think it would be helpful to allow negative values in quick add, to remove ingredients/add-ons for items that are already listed, but you do not want to create a new food just for the modifications you made. For instance - the [insert sandwich shop name here] club sandwich is already in the app and the macros are correct, but I do not add mayo. Instead of trying to find an entry that is the same sandwich without ingredients, or setting up a new food, or trying to calculate the macros to do a quick add without ingredients, I would rather just use the base entry and have a quick add that is negative fat/carbs/protein that represents not getting the mayo.
