How do I set a custom title for viewer.html ?

[AKPR2007]

Hey, i am using pdfjs v2.13.216 since it fits my needs. I was wondering if there was anyway to set a custom title for the viewer to show since it dynamically updates to the pdf file name. I've found an old post that used ?title=MyTitle but that seems to not work for me perhaps because it was for an much older version. I would like to hard code the title into the viewer. Thanks in advance for any help.
