Making salutation changes automatic

Hello all, I have worked out a salutation format that works for our organization and I go into the Names tab to update this salutation. Here is the problem - If I update Name 1 or Name 2 in the main constituent header: ie. Mr. John Smith and Ms. Elaine Jones get married and I and change Name 2 to Ms Elaine Smith, the names tab/ salutation doesn't auto change. The salutation in the names tab previous to the change said: Mr. John Smith and Ms. Elaine Jones and it doesn't change over to Mr. John and Mrs. Elaine Smith. I want it to change over automatically whenever I edit the names in the general tab. Can anyone help me out with how I can set this up to happen automatically? Thanks, Erin
