When exporting a collection (to a bib-file through BBT, for example) the order of the items changes if the export is done by two different Zotero instances even though they share the same (synced) database.

This becomes a problem when the bib-file is added to some version control system (e.g., git). Would it be possible to ensure somehow that the order is kept fixed across Zotero instances for the same collection? Maybe by sorting by "Date Added"?
