Creating new formatting theme

[usentr]

Good day,


I wish to define the following fonts for different styles in Microsoft
Word. I would like to save my preferences as a 'theme' or anyway that
allows me to preserve my settings on the new document

Heading 1 Arial 14
Heading 2 Arial 12
Heading 3 Arial 10


This setting should be saved as a theme or template so that the next
time i create a new document, i do not need to re-define theses fonts
for styles.

Is this possible in Microsoft Word 2003?

Thanks in advance
