Editing starting tech level

[adi]

Hi everybody,

I noticed in UE that in the starting conditions menus one can set the starting tech levels for the five eras.
I have 15 tech levels in my game and i'l like to move from the 1-3-5-7-9 schema to something like 1-4-7-9.5-12;

Is it as simple as changing there and hitting Auto-Set all, or there is more to it? Is hex editing needed?
Also there are settings for minors over there; i plan to let those as they are for now, since there is to much to change over there. maybe if we can have that data in a csv file at some point some automation can be made to set all those values, like with the ship stats.
