Hello Scott, welcome to Feng Office Forums!
That feature seems to have been created by someone from the Community, but it is as though as he missed attaching the actual code tweak... may be you should post in that thread asking him nicely if you could use the feature and send him feedback about it, as well as dropping him a PM.
Best regards,
Francisco
