You can control the Dashboards each Team member can access through a simple series of switches.
Click "Team Permissions" in the Team Dashboard
Below the list of Campaign Managers, you'll see the full team listed alongside switches for each available dashboard.
If you don't want someone to access a particular dashboard, just flip the switch to "OFF" for that dashboard next to their name.
To turn it on again, flip the switch back on!
You don't even need to save changes afterwards - CampaignAmp saves Team permissions on-the-go.
