Signals Notebook: Is there a way to set up a user to be the administrator of only one system group?

Details: It is necessary for the manager of each group to have control over the members of their group, but for them not to see the other groups. They need to be able to add and remove users, but only for their group. Using a combination of User Roles and Sharing levels, it is possible to set a User Group administrator that will have full control over a single group.

Steps:
1. Navigate to 'Signals Configuration' > 'User Roles'
2. Create a new role with a unique name e.g. Group Admin
3. In the 'Administration' tab select only 'Configure System' and 'Manage Groups'
4. Navigate to 'Signals Configuration' > 'Users'
5. Edit the user you wish to set as the group administrator and add the new role e.g. Group Admin
6. Click 'Save'
7. Navigate to 'Signals Configuration' > 'System Groups'
8. Open the group you wish to set the administrator for
9. Click 'Sharing'
10. In the 'Users' tab search and add the user to assign as the group administrator
11. Give 'Full Control' privileges to the user
