Nioverride and additive scaling

[foreveraloneguy]

Tried in the nioverride and racemenu threads, but never got an answer. My question is whether anyone has had success in getting anything other than multiplicative scaling to work correctly? If I set the scaling option in the ini to additive, then any character with scaling applied will spawn with that scaling applied to the character's height (like doing a setscale xx on the character) until I change some part of the scaling at which point it resets to normal height, etc.
