[NTG-context] Tracker for hyphens at the end of lines

Hi colleagues, Is there a tracker for highlighting hyphens at the end of lines similar the way underfull and overfull boxes can be displayed with a coloured bar at the end of the offending line? I have looked at the wiki page "Reviewing hyphenation" and it has a solution for mkii from 2009 which, I would think, won't be suitable  for present day ConTeXt. I have tried searching for hyphens using Skim and Adobe Acrobate viewers but although they find hyphenation in line they don't recognise hyphens at the edge of lines. Any help would be appreciated.
