when citing a preprint in bibtex, the suggested document class is @UNPUBLISHED. This requires a “note” field. However, paperpile doesn’t seem to offer such a field in the web interface for entries categorized as “Preprint Manuscript”. When I export the entry to bibtex, the field is also missing. Is there some way to manually add it in paperpile? Otherwise I currently have to open the exported bibtex file and manually add the note field for all preprint entries.
