Windows Context Menu - New > RTF Document - But with Page Layout margins set to Narrow or Custom?

Let's say I leverage the info in these following answers..

to creat a "New RTF Document" menu item to Initiate/ Invoke creation of a RTF Document.

How, can I get "Word 2010" and "Write/ Wordpad" to default to do so, using a Narrow (0.5) or Custom Page Layout?

• I know I can change Margins after opening the document. But to do it every time for every New RTF is too much effort.

• Also, I know there are some "Default" templates/ mechanisms that Word defaults to when it creates a New Document

But I am not sure if and how I can leverage them to work/ apply when a file's created via the context menu "New > RTF Document"?

• Current OS: Win 8.1 Pro - 6.3 Build 9600
• Microsoft Office 2010
