arxiv paper titles not visible on hypothes.is annotations page

tl;dr It would be great to be able to modify the name of a document/page, since pdfs from arxiv show up with just their id (e.g. 1607.06450v1.pdf)

Hello! I hope this is an OK place for a feature request. I use hypothesis to take notes on pdfs from arxiv.org, but when I review my notes on hypothes.is it's difficult to see what each pdf/page is. The list of pdfs/pages looks like this:

As you can see, it just shows the pdf arxiv id, not the paper title! So, my feature request is: can we add a way to modify the title of a document so this notes overview page becomes more readable?
