IMDb update : List of episodes watched

I was thinking, if any of you are familiar with MyDramaList or MyAnimeList, they have this feature where you can keep track of the number of episodes you have watched. And it's pretty convenient and easy to track. So i was hoping if IMDb could have this feature too, sure we have the episode list but making a individual list (or even a combined list) for all the episodes we have watched so far seems really confusing and messy.
