Hierarchical multiple stars need designations for individual components, for super-components (several bodies that act as single dynamical center and are often measured jointly) and sub-systems. Hierarchical designations like those proposed for WMC can satisfy all needs, but designations will have to be frozen and will not reflect true hierarchy in the future as new components are discovered. Hence, a clearing house (WMC on the web?) is needed to maintain unique and consistent designations. The hierarchy can be coded separately and flexibly by reference to parent super-components. As an example, these ideas are applied to a real quintuple star HR 1706.
