Permanently change safety height in Easel

Hi to All!

Is it possible to change permanently Safety Height.
I change that every time, I open Easel.
But every time that rewrites to 3.8 mm

I think I changed that once (somehow).

I figured out, that if I change the height, than that is saved in the project.
Creating new project, I have the same 3.8 mm.

Or that is usual behaviour?

Did you ever get an answer to this question? Not only do I want to change the safety height a bit, but i want to permanently reduce the step over for the v bit by a few tenths of a percent. The only thing I’ve found is that I can save it per individual file. Perhaps 1% is the lowest step over it will recognize.
