Feature: Add ingredients of recipe to shopping list, even if they are already in stock

Hi,

I want to use Grocy to keep track of my personal storage of groceries. It seems to be great for that (much better than my current 'Excelsheet of doom'), but it lacks one feature.

I'm living in a student house, with some flatmates. We cook for each other, and then share the costs. To make this easier, it's nice to just buy the groceries for a cooking session, and put the receipt on the system we use for keeping finances fair (we're Dutch ;))

I'd therefore like to have a button that says: add all the ingredients of this recipe to a shopping list, regardless of whether I already have enough in stock.

Ps. if this button already exists, I'm sorry, I tried it out in the demo, and couldn't find it.
