in North America it's letter-of-reference season for professors, and I am writing a lot of them. These are some of the only documents I still compose in libreoffice, because I need to use a letterhead that contains both image and text, and I need to insert a .png of my signature near the bottom.  I would much prefer to compose these letter in org and them export. In order to so I would need to preserve the letterhead and the signature somehow.  Both these sections in my current letters occur within the
<office:text>
</office:text>

section which I guess is always replaced by org on export.  My immediate question: Is there a way to preserve some of these contents? More generally: do people have template files they are very satisfied with? I would be happy to go straight to pdf via latex, if it were easy to accomplish the same effect that way I don't use latex at all myself so it might not be so easy for me :-/.

For completeness, here is the xml for my letterhead (sorry it's rather long):

--------------------

As you can see, one occurs at the beginning of the <office:text> element, and the other at the end. Can I somehow insert them on export?

Thanks as always for your help.
