Adding multiple files to the field "File"

[DrWaleedAYousef]

How can I add several files to the field "File" with fast shortcut (like the option "Add PDF to library)? Or even append one file to the already existing "File" list

There is currently no support for this. Modifying the bibliography more generally is currently outside the scope of helm-bibtex. I edit my bibliography by hand. For instance, I select an entry in helm-bibtex, select "show entry", and then add the PDF manually. I'm not terribly familiar with ebib, but perhaps it would make sense to add an action "edit in ebib" and to add PDFs there. Not sure.
