servings alternative - baking tins

[Silther]

Is your feature request related to a problem? Please describe.

to be able to change the number of servings is a very nice feature, but sometimes it is not enough as linear scaling does not work on all recipes.
If you are baking a cake, you cannot simply adjust the number of slices (servings) instead you have baking tins in different but fixed sizes.
many recipes have ingredient amounts for small middle and large tins.

Describe the solution you'd like

Would be nice if you could disable servings and instead create different ingredients amounts, all with an individual amount for each ingredient and selectable via an drop down menu or something like that:

small tin - 4 people:

• 50 g sugar
• 100 g flower
• 70 g chocolate
• 1 spoon salt

middle tin (default) - six people:

• 75 g sugar
• 150 g flower
• 90 g chocolate
• 1 spoon salt

large tin - 8 people:

• 100 g sugar
• 200 g lower
• 110 g chocolate
• 1.5 spoon salt

non linear scaling is something I wanted to do altough its probably going to be a clalculator that calculates the scaling factor based on different useful formulars

I'm just not sure if servings fits all recipes even if scaling gets more non linear options.
