Use a template


  Choose New From Template from the Document menu.     Edit the document.      Choose Save to save as a regular document.


When you save after doing New From Template, the Save Panel will appear just like it does when you save a new document.
By default, New From Template... puts you in a special Templates directory. There is no requirement that templates be retrieved from this directory; it's merely a convenience.
