Mark preceding episodes as watched

I would like to have the option if I play episode 15 season 2, to mark as watched every episode until this point. I feel is only natural to assume that there is a high probability that you had watched the previous episodes if you choose to watch this one in particular.


+1 for the request.

Automatically marking as watched maybe would be a little too rigid, but an option to mark all episodes before the current one as watched (1. only in the current season or 2. in all the preceding seasons) would be great!!
