Hello.

I'm working with Vatican Documents and in our field we usually omit the author from the short title in papers. I'm using Chicago. Is there a tag or way to suppress the short title author on a particular entry.

Examples:

Pope Francis, “Apostolic Exhortation on the Proclamation of the Gospel in Today’s World, Evangelii Gaudium,” The Holy See, November 24, 2013, http://www.vatican.va/content/francesco/en/apost_exhortations/documents/papa-francesco_esortazione-ap_20131124_evangelii-gaudium.html#Star_of_the_new_evangelization.

Short Form that is Generated:

Pope Francis, "Evangelii Gaudium,"

Short Form I'd Like:

"Evangelii Gaudium,"

Thanks for your help!
