This is only possible if the feature is programmed into a particular sample set. Hauptwerk does not offer a "master sostenuto" function.
I believe that only two "classical" organ sample sets offer a sostenuto function (which you could connect to any MIDI control/switch): Voxus's Kuhn/Essen Philharmonie and Inspired Acoustics's Palace of the Arts/Budapest (PAB). Both of which are concert hall (non-church) organs. Other than those two, it's just the theater organs.
