When streaming a movie on Netflix using Apple TV, how can I turn on subtitles for the hearing impaired?

I guess no one from Apple ever reads these discussions because several people are asking the same question and get no responses. What is the point of these groups if you can get answers? I, like many, am severely hearing impaired. I need subtitles (closed captions for the hearing impaired) in order to watch a movie. Netflix provides this functionality on many of its movies. It works with my iMac but not (or I don't know how) to get it to work on my AppleTV. I need this functionality. Is there a way to do this now? If not, is Apple planning on updating its AppleTV with this capability? If so, when?
