You can add an export menu of your own:

(defun my-src-block (src-block contents info)
  (concat "got you\n" (org-latex-src-block src-block contents info)))

(org-export-define-derived-backend 'my-latex 'latex
  :translate-alist '((src-block . my-src-block))
  :menu-entry
  '(?z "my special exporter"
       ((?o "pdf and open" (lambda (&rest args)
     (let ((texfile (org-export-output-file-name ".tex"))
   (pdffile (org-export-output-file-name ".pdf")))
       (org-export-to-file 'my-latex texfile)
       (ox-manuscript-latex-pdf-process texfile)  ;; scimax function, you
might do something else here.
       (org-open-file pdffile)))))))

Then: C-c C-e z o
