VTT - Private Encounters

I don't believe the current version has this functionality...if it does I can't find it.

It would be very helpful if I could setup an encounter in the Maps VTT and run some private simulations with different monsters...being able to roll all the dice in the VTT but have it be private so that the players wouldn't see me doing it in their Game Log.  Even if you set the dice at the top to only roll to Self, if you start the encounter I can see the roll on my players Game Log if I log into their character.
