Is your feature request related to a problem? Please describe.
I am using helm-bibtex and biblio.el which allows an extended download action to retrieve the pdf from arXiv.
The issue is, that the file is wrongly named and saved to the org-directory.

Describe the solution you'd like
I would like the filename to adhere to the file name convention of org-ref and org-roam-bibtex (including the autokey pattern).

  (setq orb-autokey-format "%a%y")

Additional context
I have looked at biblio.el at https://github.com/cpitclaudel/biblio.el/blob/55a72b5cd41325d8c98a73932ef3a7b0cf71ea63/biblio-download.el#L37

I don't know how you would imlement this. I would have overwritten the function of biblio and adjusted the file name according to the rest of the configuration. I wondered whether there is a function ready to use to convert the record from biblio to a citation key. Since you are pulling from different libraries already, I thought it would make sense to ask this question here.

Much love and thanks for the packages!
