A stat on how long it would take to finish everything

A statistic on how long it would take to watch everything would be good. It would be great if it could list it as movies, tv, and then the combined. So say for example everything that I haven't watched might take me 8 months and 6 days and 4 hours. And better yet if you could click into that stat and it would bring up everything on your list, then that way if there's something you don't even want on that list anymore you could delete it from there.
