Do any Flex MARS users *share* their radios over SmartLink with other MARS members?

Briefly, I am experiencing an issue that I plan to submit to Flex support soon but since it deals with MultiFlex actions that I can replicate only on frequencies outside of the Amateur band it would require someone with a MARS turfed radio to confirm (or Flex Support).

Another local MARS member and I are remote from each other and sharing my 6700 over SmartLink. I am using SmartSDR (3.1.7) on my PC and he is using a Maestro control head (version . We are both sharing my SmartLink password to access the radio.

1. When we are on the same frequency inside the 75 m Amateur band we can listen to the other transmit when the MON button is selected and each of us can operate MON independently (this is a good thing).
2. But, when we are both on an adjacent MARS frequency then any local MON button setting (on/off or volume change) is reflected immediately to the other operator (this is NOT a good thing).

The consequence is that if my friend is transmitting, and I want to turn up the MON volume to listen to him, then his own MON volume is immediately adjusted by my actions... and he then hears that delayed, and annoying, feedback of his own transmission into his own headset. From his point of view gremlins took over his Maestro and gave him grief. But it turns out that I was the gremlin and didn't know I was impacting him. 

We can replicate this and so I will submit a ticket to Flex.

Is there anyone else out there that can duplicate this condition? It seems to be dependent on if one is inside or outside a proper Amateur band.
Thanks.
