Oh - I forgot that you could do multiple schedulers in the trigger.  The only problem is that I have to trigger 1 scheduler N times with different properties.
For context, I want to query the repository for the set of parallel tasks that I should run post-merge.
Then I want to trigger the same scheduler N times but with additional properties set so that it knows what task needs to be run.
