Can we create multiple files from a file template

If I create a new html template I want it also to create a javascript file as well.  It would be usefull to just run another file template or multple templates from a main template

Example could be having a box in a template that says run templates and you could also pass in the same name or a new name based on variables.  So if I have defined a custom html template and a custom javascript template I can call the javascript template from the html template.  Which would result in creating two files both the html and javascript files but you can call as many other templates as you want.  You could have a template that calls a template and that template calls another template ect ect...
