how to enable pdflatex --shell-escape switch in org-export dispatcher interface

Question

I would like to add a switch when invoking the org-export dispatcher interface for latex-pdf exports. I'm trying to render an SVG image but the *Org PDF LaTeX Output* buffer errors out because of a missing commandline switch --shell-escape during pdflatex compilation. The result is a PDF that does not render my SVG image. So, how can I add this switch to my pdflatex compilation when exporting from Org Mode?

Something like this in your init file should do the trick.

(setq org-latex-pdf-process
      '("pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
    "bibtex %b"
    "pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
    "pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"))
