Say you have system A and you have system B (that is part of system A). Say you have stage called test and you have a stage called deploy. At the moment its not possible to first test system B and then deploy it and then test system A. Off course its possible to change the stage name on the test for system A and call it for example Integration test. But in some cases, when the process is complex you want it to be the same name to get a good looking pipeline. It might be some cases where its a test for system B and also a test for system A and not a integration test. I am not saying it should be possible to go backwards in the pipeline. The thing I really want is to be able to have different levels of the same stage. So if a stage has already appeared in the pipeline it should be possible to use it again but on another level.
