I would LOVE for a deployment step to be able to start another package. Example for use, which is very very common: Department A has standard software of package A, B, and C. If the packages each have 5 steps, it's time-consuming to copy and paste all the steps into a "department" package that installs all the software in one step.
This has been requested by several customers and our development team is aware of this request, but we do not have a release date for this feature unfortunately.
