Notes:

• Only Enterprise, Unlimited, Performance, and Developer Edition users can give access to a public groups or roles.
• We recommend this method as a workaround. Managing several public groups with just 1 or 2 users becomes unnecessary overhead for System Administrators.
• If using "Grant Access Using Hierarchies", the manager of the member also receives access to the list view shared to the Public Group intended for just the selected user
