Access the Editor Subsystem #865

Hi, I wonder if this is a missing feature or maybe I am missing something, but I've been trying to get the editor subsystem by using the EditorEngine class and calling the method GetEngineSubystem to pass the MoviePipelineQueueSubsystem object.

I've tried to use it directly EditorEngine().GetEngineSubystem(MoviePipelineQueueSubsystem) and by using something like EditorEngine().call_function("GetEngineSubystem", MoviePipelineQueueSubsystem) without success, it says the function can't be found.

Any help around this would be appreciated.
