Update database by adding bib file repeatedly

Hello!

I was wondering if it was possible to keep cobib's database up to date by constantly re-adding/re-importing a bib file? With zotero, I'm able to export a bib file and keep it up to date automatically when I have new entries. So I was hoping to have a simple script that would constantly run the command cobib add --bibtex <path to bib file> whenever that file changed. The problem it seems is that if there is an entry in cobib's database that's also in the bib file, cobib exits with an error. It'd be nice if cobib could simply ignore duplicates and continue attempting to add entries until the end of the file. What are your thoughts on this?

Alternatively, I'd be happy to ditch zotero altogether if there was an easy way for cobib to integrate with qutebrowser to add entries to the database, similar to qutebrowser-zotero.
