As a Product Manager, when I change an idea status, I want a default admin response to appear automatically. I could then tweak this pre-populated response as necessary and publish it. This would save me a lot of time during our idea triaging sessions.
For example, when I triage an idea to "Unlikely to implement" (which is a status I've created), I'd like the admin response to populate with the default admin response I've set for the "Unlikely to implement" status, which is, "Given the limited interest in this feature, we have decided not to build it. If you think we should reconsider, please vote on this item and give us specific feedback on how this impacts your business."
