Creating user groups is a great way to generate reports that only include the people you want. You can create groups for the team you manage directly or for each office in your organization. That way, you can focus closely on a few people without getting distracted by everyone else.
To create groups and add users to them, go to the Team Members page, under Management, or move your mouse near a user's name to reveal the groups selector. Click Add/edit groups to create groups, then select which groups each user belongs to.
There's no limit to the number of user groups you can create or the number of groups a user can belong to. Report filters are remembered between sessions.
