Allow an Admin Response for Ideas that are "Unlikely to be..." or "Will not be Implemented" without exposing the idea to the Ideas Portal

Sometimes we will receive an idea that is either inappropriate for our product or we just have no plan to implement in the future. It would be great if we could give an Admin Response in this case as currently the submitter does not receive notifications unless we actively expose the idea to our other clients on the portal. Our only other option is to email the submitter outside of Aha! but this may paint the rejecting party in a bad light.
