feature request: allow inserting data based on serving size

[DavHau]

In the country I'm currently residing in, supermarket products only state their macros per serving size, like 36g for example. They do not specify it on a per 100g/ml basis.

Since the app forces me to insert macros on a 100 g/ml basis, I have to scale up all the numbers first before typing them in, making the process not enjoyable.

It would be great if the app would allow me to pick another basis than 100 g/ml to insert the data.

My workaround is to add the food in Open Food Facts. It’s not ideal, but at least we’re making the community better?
