You can save any project as a template which is a choice when you use "save as"
Or what I do is just save a blank CWP file with all my tracks and in/outs set the way I want them. It's really the same diferance.
But now I mostly use TRACK templates as they are super fast to add to any project.
Just open a blank project and populate it using track templates.
IT IS A GOOD PRACTICE TO ALWAYS SAVE NEW PROECTS USING "PER PROJECT" folders. That way the audio will be saved with each project instead of jumbled together in one huge folder.
