rst2html link to given page in pdf document

I wish to link to a given page in a pdf document from the html document 
generated by rst2html:

The following works (in the rst file) - :download:`GA 
<../LaTeX_docs/GA.pdf>`
to open GA.pdf at the beginning.
The following does not work - :download:`GA <../LaTeX_docs/GA.pdf#page=12>`
to open GA.pdf at page 12. However if I use - :download:`GA 
<../LaTeX_docs/GA.pdf>`
in the rst file and then change - _downloads/GA.pdf
in the html file to - _downloads/GA.pdf#page=12
then the link does open on page 12. Do you know of anyway to code this 
directly in the rst file?
