When you do a file-render as, you pick the file type and template you wish to use. If you want, you can also click on Custom, make some changes, and save that as a new template. So, yes it is possible to create a new template but you should not get a “new template file” in your render directory.
Once you’ve picked the file type can template and click to render, you will get a SINGLE output file of that type unless you subsequently do it again OR you use a script and have picked multiple output formats.
