Yes.
I've dog-eared item six in here as well. I agree that you should be able to separate the wheat from the chaff, and you should be able to triage complaints as they come in. Is your recommendation here enough to give you the power to be able to say, “Well, we answered a similar complaint last week, and we don't need to go through all the steps again”?
I guess we want to do what we can to free you up to be able to be as effective as you can without being repetitious or dealing with.... For instance, what if a complaint is malicious or vexatious? Do you even have the right to make that judgment call and disregard a complaint on that basis?
