You can configure Rise to automatically assign managers according to the team or department to which the employee is assigned. When the team or department lead is set, the members of that team or department will automatically have their manager updated.
To use default manager assignments:

You can use a combination of both the team and department lead. If both options are selected, the team lead will take priority over the department lead. For example, if an employee is part of a team with a lead, as well as a department, the team lead will be set as their manager. If the employee is not part of a team, or is part of a team with no lead, the department lead will be set as their manager.
