Powershell Commandlet to be able to set Workflow State Security on Templates.

I have 25 districts and we have a workflow that has 15 steps. In the folders in our template there are 5 division users that are set on all templates/projects but there are also 2 folders with 5 district user lists that get applied. So it is an extremely labor intensive activity. We need a way without having to build out 25 or 50 workflows to implement this where it can be maintained.
