Nested groups
You can create groups of groups. To assign a group as a member of another group, you select that group as the parent group. For example, to make Group B a member of Group A, when you configure Group B you select Group A as the parent group.
Dynamic groups can be members of static groups and vice versa. Nesting is limited to eight levels in depth.
