You can use an autoexec.cfg file to tall the game what to load but when I tried that the game would constantly crash.
There is also a user.cfg file you can make but Im not sure hot to get that to work (I haven’t really looked into it t.b.h).
Another way is to make a .txt file in the KD:C folder and name it whatever you want (custom.txt) and put all your settings in there.
Next time you load the game go to the console and type “exec custom.txt” and that will load all the settings inside that file.
