So could you re-explain assuming my piepline object is created by 

pipeline = PipelineController(...)

?

pipe.add_step(name='stage_train', parents=['stage_process', ], monitor_artifact=['my_created_artifact'], base_task_project='examples', base_task_name='pipeline step 3 train model', parameter_override={'General/dataset_task_id': '${stage_process.id}'})This will put the artifact names "my_created_artifact" from the step Task, on the main pipeline, automatically
