Bot difficulty in combat training

Hello,

How can I change bot difficulty in combat training? I`ve found the console variable bot_Difficult_default that I can change to veteran (default regular) that work (bots spawn lv 60) , but also the game put me in spectator mode when starts a combat training session.

Edit: Tested it today and I played normaly using this command (bot_Difficult_default → veteran). Would be nice if this change persists when open the app again, but I guess it is hardcode so requires to recompile the code.

Thanks
