I wonder if this is still hidden in the latest M4L API?

I have an instrument rack with several synths (Absynth, Omnisphere, etc.) each of which have been set up to receive program changes. Those programs appear within the device as menu selections. However, I can't seem to access them, as the entire device seems to be hidden (I can send program changes, but I'd like to access the menu items themselves). There seems to be threads on this topic as far back as 2011: https://cycling74.com/forums/accessing-devices-within-the-instrument-rack

Has anything changed since then?

Thanks in advance!
