Everything of WideAngle is broken down by 'Roles.'
Within the "Manage Accounts" section of the application, there will be a subsection that will allow you to manage the roles.
Here you can manage your team's Roles. These roles do not have to be the job title, you can separate out teams based on seniority, job function, or even day of the week. The thing to remember is that the Brief is tied to the role, so for every role that reports to you, you will have a separate Brief.
