Can I insert a PDF into a course slide?

Hi All, 

Does anyone know if I can add a PDF document to be viewed as a slide?

I want to insert a glossary into my course and I would like to do this using a lightbox slide which contains a table which is pdf's word doc.

I can't see an option to insert a doc so I'm wondering whether this is not something that is achievable in Storyline?

Thanks,

Louis
