Creating a .docx document with the right mouse button

Hi everyone,
Is it possible to set a feature that when you click on the desktop with the right mouse button and choose “create new document” instead of creating it with the default extension .odt it creates it in .docx?

Same thing for xls, etc. too.

Thanks!
Nunzio.

(shouldn’t this question appear in English branch, since you phrased it in English? :-))
