Hi there,

I’m using `plugins/downstream` to put a pipeline together that based on repo A building successfully (when master) it will then trigger repo B. So far so good, however I would like to trigger particular build steps in repo B only when the build is triggered by repo A.

Is that possible? So far I cannot find anything in the documentation that mentions such a feature.
