Actually there is more than one way to do that with some notepad magic.
The way I do it, whenever I get my mitts on a new version of Strive I go to Gamefolder/assets/data/Traits.gd and swap out all instances of l_cost = 1 to l_cost = 0. That's it. No messing with saves required.
Of course I do more than that and to other gamefiles too, but that would be telling.
