Change Record to Show Last Updater Not Creator?

[Phillyman]

I mass created 95% of the database records on my site. It is somewhat discouraging to my members to see my avatar everywhere when they update a record to add information. Is there a variable I can change in the display templates to show the username/avatar of the last person to update a record, rather than the creator of the record?

 

This is what shows....

 

 

This is the last person to update this record (shows in Revisions)
