You could add a hook to remove headlines with a "prelim" tag:

--8<---------------cut here---------------start------------->8---
(defun my-org-export-remove-tagged-headlines (tag)
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward (concat ":" tag ":") nil t)
      (delete-region (point-at-bol) (point-at-eol)))))

(add-hook 'org-export-preprocess-hook (lambda () (my-org-export-remove-tagged-headlines "prelim")))
--8<---------------cut here---------------end--------------->8---

Best,
Matt
