I'm not an administrator, so this may be in the wrong forum. Thanks for your patience.
I supervise about 15 field technicians in several states. Each tech has his own shared calendar. Which I turn on or off as needed.
For the sake of speed, accuracy, and efficiency, I would like to be able to turn on all techs in a given state (a group?).
Just to clarify when I say "turn on" I'm referring to the ability to make a tech's calendar visible to me.
