The My Template projects location is used to specify the default location to save your template projects. Can you please tell me know what snippets you are trying to include and the entire use case? This will help us in understanding the issue better.
When a new project is created,it created a main (for example main_cm0p.c) which seems to follow a template. Is it possible to change that template (just the header comment part?
You can create your own template project and create your project using the template. Please refer to My Templates section of the PSoC Creator User Guide.
Thanks and Regards,
