Cubase 6 - batch export files as they appear in the project?

I thought I could easily create stems from my projects using the “batch export” mode, but not so fast! When I export the individual tracks ALL of the files produced are stereo files even if they are mono tracks. And if I select the “mono downmix” option ALL the tracks export as mono files even if they are stereo tracks.

So, is there a setting to export the tracks as they appear in the project, i.e., mono files for mono tracks and stereo files for stereo tracks?
