Option to be able to pin someone automatically when we reply or send new mail.
We PIN all the "must" people in the CC so it will save our time in putting all the people in the CC everytime we send mail.
Plus, since there are a lot of "must" people to be filled out in CC, there may be some mistake to not include some people. We would like to avoid such problem.
