How to add a file creation template to the list of NetBeans templates?

Question

IDE

I'm trying to create a less file in Favorites. A window for creating a file opens, and there is nothing except the jade template.
At work, I have a whole list there: less, html, and so on.
Moreover, everything is in the templates, and if you work in the project, and not through Favorites, these templates are available.
How can I add other templates to this list?
