This function sorts multiple destinations registered in this machine into a related group (reference allowed group) such as a group of customers per department.
Set a reference allowed group for each user to limit access to destinations. For example, assume that Group B is set for a certain user as a reference allowed group. In this case, that user can access destinations in Group B, but cannot access destinations in other reference allowed groups.
Register a reference allowed group on this machine. In addition, assign a reference allowed group to the destination and user.
