I've done this in the PitchFactor.  I believe that each of those "extra" 28 presets all contain what's currently in the edit buffer (last loaded preset plus whatever manual 'tweaks' that were adjusted after loading).  I'll have to confirm when I get home, but I seem to remember the 101-128 MIDI presets as having the name of the preset "jumped from", but with an equivalent preset number matching the received Program Change message.
