Sorry, no. It's just something we haven't considered.
What I would recommend is editing the recording in Audacity (which is a free download) to blank the defective channel, and probably duplicate the good one. Then you can do your track splitting and any further audio cleanup in VinylStudio in the usual way and end up with mono tracks, once saved.
Audacity can be a useful adjunct to VinylStudio from time to time. VinylStudio can do most things, but, being a dedicated audio editor, Audacity has some features that VinylStudio lacks (and vice-versa, of course).
