Able to add a PDF to an "Update-new comment"

[#1]

—It would be great to be able to add a PDF to an Update "new comment".

—When we are updating teammates we have a lot of pdfs we work with as a multi-page file that we find it valuable to add the the "new comment" in Updates so support what we are explaining.

—It would be beneficial to be able to add a pdf as well. Right now only pdfs can be added to Documents or as Proofs.

—Currently only jpgs, pngs, gifs can be added to an Update comment.

Agreed, this would be far more useful if PDFs were allowed.
