2 Magnum PT-100 controllers and 1 ME-ARC remote

Is there a way to use 1 Magnum ME-ARC remote to monitor 2 PT-100 Magnum controllers? My PT manual says stacking is not supported at this time but I was told that a special cable can connect the 2 controllers together into the inverter. I have my second controller coming in a week and a Magnum MS4024PAE inverter coming at the same time. There is no instruction from Magnum on how to connect the cable or allow the remote to control 2 controllers so I am a little confused as to how this is supposed to be done.
