Set up your tournament the way you like (including having the various templates you want loaded). Save it. Then go to the Preferences tab and press the "Config Files" button. In the "Default Tournament" section (at the top), select "Use tournament file:" and press the "Browse..." button. Find your saved tournament and select it. Press OK on dialog to close it and save your changes.
Now, when you start the software, or when you press the "New" button on the Game tab, it will use your saved tournament as the basis for a new tournament.
