Is your feature request related to a problem? Please describe.
I'm working on abookdown project, so I have multiple Rmds with citations. I'd like to import a messy central.bib file for all of these, and then clean it usingtidy_bib_file().

Describe the solution you'd like
I'd imagine that the solution would be that a call oftidy_bib_file() onindex.Rmd would look up all the child documents through_bookdown.yml, and then applytidy_bib_file() to each.

Describe alternatives you've considered
Keeping an updated.bib file through Zotero from specific collections and manually removing entries when I remove them in the text.

Additional context
This is all in the context of a PhD thesis. I'd like to either end up with one cleanreferences.bib, or maybe separatechapter_1.bib,chapter_2.bib, etc. files if I end up converting them into articles. But I think ultimately, a central.bib file from all Zotero entries that is subsequently tidied would work best for the most contexts.
