Currently "Wait for Previous Commits" waits for *all builds* on a buildable to finish.
In my scenario, I have a set of regression tests which are expected to take hours. This is in comparison to the normal build + functional tests which take around 5 minutes. I want the normal build + functional test to wait for previous commits, because this is the build plan that actually publishes things, but not wait for the regression tests (because that will mean each commit takes hours to build).
So I'd like the ability to set specific build plans on the "Wait for Previous Commits" build step and only have it wait for those build plans to finish on previous buildables before continuing.
