Marking episode as watched

Dont know if there is a work around for this but I am having troubles with having episodes marked as watched.  I have been going through a series and get to the end of an episode and may not watch another one immediately but the previous episode that I watched is not being marked as watched/sparatically correctly being marked as watch.  When going back to title page, I did not see a way to mark the episode as watched so that I can keep track of progress.  Any work around/help?
