You can set the default project template by first creating a project, setting it up exactly as you want all new projects to be and then click the 
in the File Menu. Then, every time you create a new project, it will start off as a mirror image of the default project you saved.
The file is named Default.project and is in the library '___SystemDoNotRemove' directory .
You can always reset the default project to the factory default using the File Settings.
