Ability to Edit Success Plan Fields via Rules Engine

While it is possible to create a  new success plan via the rules engine, it would be great to be able to update it or the Success Plan table as well. This would allow us to keep users in one place instead of having to jump back and forth between systems to make sure they have the most up to date information. 

Additionally, this would allow us to add additional details to a Success Plan and how it is tracking towards completion based on how we define progress (weighted values for each  Objective)
