I'd like to change the title of my report, and the exported pdf filename, based on a value I can change in the org-mode source.

I have a source block like this:

#+NAME: reporttype
#+BEGIN_SRC elisp :results value silent :exports results
"Foo"
#+END_SRC

I figured out how to do the title:

#+TITLE My Report: call_reporttype()[:results raw] Results

which is pretty neat (but wasn't easy to figure out, I'll work on that in the doc).

...but I'd also like to set the exported PDF filename based on the reporttype, but I'm not sure there is an option for that.  Is there?  And if there is, is there a way to interpolate my reporttype into it?
