Disable Webcasting by Group?

[MikeBwca]

According to the BI Help, in the Webcasting section, it states...

Consider disabling webcasting of the “all cameras” group altogether.

But, does not say how to do this. I cannot find any 'group' webcast setting.

Other than disabling 'Webcast' per camera (which would also disable Webcasting in all groups the camera is in!), I cannot see how to do this.

Anyone know if there's a way to do this?
