Help ! Multi-channel setup division routings

Does anyone have experience with running organteq in a multi channel speaker setup (4.1) with Ableton and Envelop for live (E4L). How do you route the channels from organteq ?

Great, swell, pedal - front speakers
Recit: rear speakers
Reverb ??? - all channels?!
Pedal - front ?

How about the reverberation settings/mix ? Ideally the reverb image you would experience from the console/organists perspective. I guess it is not equally between front and rear.
 
Organteq output.    Organ work         / SignalE4L Panner Positioning.   Sound effect in space
——————————————————————————————————————————-
Channels 1/2.        Great (main work) Front (centered / wide).               Forms the powerful foundation directly from the frontspeakers.

Channels 3/4.        Swell (Swell).        Middle to slightly back.                Can be dynamically moved to the rear via the Panner (simulates the opening/closing of the sill doors in the room).

Channels 5/6.        Recit (Choir).         Slightly in the back of the organist - narrow to medium wide
   

Channels 7/8         Pedal (bass).        Front (centered).                          Low frequencies are difficult to locate, but come best from the front for the pressure.

Question:
Organ Reverb (Hall) Rear (Wide) Is placed completely on the rear speakers. As a result, you "stand" in the middle of the nave.
Any idea how to route the reverb only to the rear speakers or at list to control the mix between front and rear ?

Did Modartt say anything about this ? The reverb is one of the key factor for the typical organ sound which always need to be in a 3d space…..I wonder how many organteq users have the possibilities to do this rather than listening in stereo setup ?

Any suggestions for the recipe?

Tks in advance
