Obtain listing of all groups defined on HannonHill server via SOAP

Looking for a way to get a listing of all groups(EntityTypeString=‘GROUP’) that have been defined in HannonHill. I originally posted question in ‘How do I’(http://success.hannonhill.com/cascade-server-forum/how-do-i…/get-list-hannonhill-groups-via) and was told this functionality does not currently exist and to add as a request here.
