[question][creationkit] How to create fillgrades for bottles?

[worik]

I am looking for a way to implement some kind of variable fillgrade to drinking bottles and potions.

 

Until now, I have seen a technique where a "full" bottle gets replaced with a "half full" bottle if it is used. (Realistic Needs and Diseases)

But I think there must be a more refined method to do that.

 

Has anybody seen any mods do things like that?

Any ideas how to do that?
