                Used to restrict updates/request to a list of specific CompID/SubID/LocationID/DeskID combinations. If not present request applies
to all applicable available counterparties. EG Unless one sell side broker was a customer of another you would not expect to see
information about other brokers, similarly one fund manager etc.
