In September, my office (AFG) changed our public zones. Because of
  the scope of the zone changes, all of our zone numbers changed. In the
  IRIS obs monitor, most stations show the old number. There are a few
  stations that show the new number although we did not take any action
  to edit these stations. Is there a quick way to update all of the zone
  numbers in the obs monitor at once or does someone have to go through
  and edit each station individually?
