Hi, first of all, thank you for notmuch. I have been using notmuch happily for several years. Is there a way to somehow hint notmuch to display messages as thread based on for example regexp? Example: Emails from servicedesk@useless.ticket.system.which.does.not.track.threads.com would show one thread for Emails with subject BF-INC-1234 and Emails with subject BF-INC-1235 as another thread.
