I don't know if this helps, but I have postamble requirements in each 
file that I export. I believe you can do the same for the preamble. 
Below is an example from one of my files.

----
* COMMENT Postamble Settings

#+BEGIN_SRC emacs-lisp

;; Turn off postamble creation
(setq org-html-postamble nil)

;; Turn on postamble creation (default)
(setq org-html-postamble t)

;; Postamble format for lessons
(setq org-html-postamble-format (quote (("en" "<p 
class=\"author\">Author: %a </p>
<p class=\"email\">Email: %e</p>
<p class=\"creator\">%c</p>"))))

;; Postamble format for non-lesson pages (default)
(setq org-html-postamble-format (quote (("en" "<p 
class=\"author\">Author: %a </p>
<p class=\"email\">Email: %e</p>
<p class=\"date\">Date: %T</p>
<p class=\"creator\">%c</p>"))))

#+END_SRC
