Suppress comma after authors in a private communication?

[jsdodge]

Hello, I would like to cite a private communication, using the following format:

A. Brown and C. Davis (private communication)

Currently I have this in my collection as an "E-mail" item type with the authors "Brown, A." and "Davis, C." and "tex.note=(private communication)" in the "Extra" field. However, this adds a comma after the author names:

A. Brown and C. Davis, (private communication)

Can anyone recommend a way to format this entry in Zotero that will suppress the comma?

I think you can best ask on https://tex.stackexchange.com/ on how to do this given your bib(la)tex entry, then we can work on making BBT produce whatever changes they propose.

Thanks—I'll follow the solution given here.

And you are able to generate this (with sufficient ease) with BBT?
