Here's a somewhat roundabout way of achieving something similar:

#+BEGIN_ORG

#+NAME: test-dir2
#+BEGIN_SRC sh :var dir="." :results output org :exports none
echo "
,#+begin_src sh
cd $dir
,#+end_src
"
#+END_SRC

#+CALL: test-dir2(dir="~/org") :results value raw :exports both

#+CALL: test-dir2(dir="/var/www/") :results value raw :exports both

#+END_ORG

HTH,
