Is it possible to have Gmail automatically label emails based on existing labels? For example, I have "Follow Up" and "Waiting Response" labels. What I would like is for Gmail to automatically relabel a conversation from "Waiting Response" to "Follow Up" when I receive a reply. I do not want to "Follow Up" all incoming mail, and I don't always want to "Follow Up" particular people or addresses.
I am well aware that I could simply flag important conversations and look to see whether I was the latest respondent, but I want an automated system for a series of reasons I won't bore you with.
So, is it possible?
