Retroactively changing name for track changes?

It looks like this might not be possible but want to confirm.

I’ve managed to change my name that shows up when tracking changes in a Word document. However, it took me a while to get around to it and most of the changes just show up under the name Microsoft Office User. Is there a way I can make the name change retroactive?

Not sure if the microsoft-word-2016 tag is correct, it’s Microsoft Word For Mac, version 16.66.1.
