What you can do is have a dropdown list in HTML with these menus
Hold
Open
Closed
And Print the status at the to as the review is open or on a hold
When a review is open admin1 can have it put on a HOLD which sets a flag to hold so that other admin cannot review it
When he has finished he can change staus to OPEN for the other admin to to review or simply CLOSE it so that the issue is bundled up
I hope this helps
Just FYI you can use javascripts onChange for this
Hope this helps
