[JENKINS-9263]  Downstream Build View does not recognize parameterized build trigger 

Related to https://issues.jenkins-ci.org/browse/JENKINS-9263

Anything preventing us adding DownstreamBuildViewAction for a build object already at the beginning of a build? This way we can add builds triggered within a buildstep as a downstream build to the action. I've tested this to work when using "Parameterized trigger" plugin to trigger builds within a buildstep.
