N3vomastercomCustomization¶https://docs.mastercomfig.com/9.5.2/customization/custom_configs/
You can use user customization files to override specific settings in mastercomfig.
These are autoexec.cfg, which runs at game launch, and the 9 class configs (scout.cfg, soldier.cfg, pyro.cfg, demoman.cfg, heavyweapons.cfg, engineer.cfg, medic.cfg, sniper.cfg, and spy.cfg) which run on switching to a new class. All of these files go into a folder called user you create in tf/cfg.
If you don’t have these files, you can download the mastercomfig template and move the user folder to your tf/cfg/ folder to customize the config.
If there’s something you’d like to run for all of your class configs, you can add it to tf/cfg/user/game_overrides.cfg
