Is MultiProjectImporter used for different law courts?

different courts have different data,such as the nlu.yml, domain.yml and action.py;and they also have some same data,

I use the MultiProjectImporter,and how to set up the action_endpoint url. Is each court has one endpoint.yml,or I use only one endpoint.yml for all the courts? and the action.py?only use one for all courts or each for different courts?

can there each court has action.py?or only one action.py for all?
