Quick and dirty would be to manually update and append "Thread Closed [n]" to the header with a message like this: ADP Begins to Roll Out a Zenefits Competitor; Thread Closed [n] Where "n" is simply a number that is listed elsewhere that describes the reason for closing. Note that can scale to any number of reasons or explanations either existing or new as if it's a footnote.
