Please let me know if i need to post somewhere else or differently as this is my first request for adding a year.

Hello.
Yes, only the referee can add a new date line for pages with locked dates. Therefore, I would suggest that you add any supporting links or images with new dates in your post. Also, I would suggest to write directly to the referee about your request.
