Solved! Although I've yet to try it in practice.
For those that have the ability to image past the meridian, it possible to set up a precise point where the mount will flip. For example, if say theres a portion of the horizon that is obscured, or may be limited by clearance, you can now define this in sitetch.cfg (Tab Mount Parms - Overpole and Under Pole). In the config file that Lucas had provided, it was set up not to flip (bended knee arrangement).
This will be handy in my case as I should (?) be able to independently set the meridian limits East, West and altitude (or horizon file) to precisely control the flip position.
This information is in the Help on the Mount Parms config tab, but is not in the older Operations Manual.
