Unfortunately, OpenStudio model objects do not have a field to store the id separately from the user name. The OpenStudio gbXML importer stores the CAD object id in the OpenStudio model object name, the idea is that id is a more reliable identifier to refer to objects in the gbXML file and in the future if the gbXML file is re-exported and merged with the OpenStudio model. If OpenStudio were merged to store user names then the ids would be lost. It is possible to make this change but we would need to consider how this would affect the workflow where a gbXML is re-exported in the future and merged with the current OpenStudio model (e.g. to pick up new geometry from Revit but preserve HVAC defined in OpenStudio).
