How do I update the names on the bubbles in track changes

[loudezseran]

I am editing a document along with two other people. When the author looks at the reviewing pane in track changes, the pane has my name as well as the two other people's names listed as editors along with our edits and comments. I would like the names associated with the edits and comments to just say 'author' rather than giving all of our actual names. How do I make that update?
