There are sets of common steps that we very often want to "bookend" all of our deployments with. One concrete example would be: sending out a Manual Intervention to confirm when all servers are confirmed live before stamping a new deployment in NewRelic.

Right now, everyone has to bake these steps into their own projects by adding the Manual Intervention step followed by the NewRelic Deployment Stamp step. If it were possible to create what I would call "Composite Step Templates" then I could define a reusable step template that was made up of other step templates. That way, instead of everyone having to repeat all of the possible steps in their own projects, they would simply include this one composite step and they'd be done.

Now, my composite example was only two steps to keep it simple, but you can imagine maybe a composite is made up of more than that. Or even imagine a change in policy where the Manual Intervention email has to include more information. Everyone has to repeat this stuff in all their projects and having the ability to put it into a composite step would alleviate all of that.
