Starter roadmap isn't tied to data in the app

I find that in many situations when coming up with a roadmap you are going through iterations and different options on how you can tackle the next period of planning.  it would be nice to have a lighter way of doing that didn't actually create releases and feature within the workflow.  

there could maybe be a stage that they start in like that and then are promoted to being "real." 

starter roadmap looks good all in all, but this would make me more inclined to use it.
