how do you have integration using scauto or CIT? Do not know much about CIT but in scauto seems to be possible and OMU expert will be required. Since scauto use event-services hence have to mention the map name in scauto and in SM you can register/create with same name.
or otherwise use triggers but it will disable the feature of auto update/close form omu as no id will be in sysnc with OMi and SM
