Create Change Request in Dimensions RM using Dimensions RM web services?

Is it possible to create a change request in Dimensions RM using the Dimensions RM web services? Using the services provided in rtmService.wsdl I am able to create a new object, but I do not see a service to create a change request. I am not sure if there is a way to use the CreateObject service to create an object in the Proposed status, essentially creating a change request, or if I should be looking for another service.

If a service is not available in Dimensions RM to do this, is there another way to generate a change request programmatically?
