Hi, about custom export filters, is it possible to export only the number of the month or the standard Bibtex abbreviation or the field as written in the JabRef database instead of the full replaced string?

Thanks for the answer and sorry for asking at the wrong place.
I will repost my question because using the search engine of http://discourse.jabref.org/ provided no answer.
See you there, maybe.
