How do I create project scope file templates and share? Follow

Hi, as the post title suggests, what I am trying to do should be very easy. 

I read the File Template instruction. It did mention the option of project scope templates but did not show how. There are no way to specify a template's scope when I create it.

In the instruction, I see the where the templates are saved so I figured I create some templates, find it and put it under the project scope template path.

Well, those directories do not exists. I cannot find any file or folder named fileTemplates under the suggested paths. I also checked synced folders (jba_config under AppData). 

Then I read the setting layer  and found my custom template here, but have no idea what to do about it. Do I copy this line and ask my colleges to paste it into their settings just to share it? 

Please help an upset coder. It really should not be this hard. Thanks.
