Watch missions needs a way to remember which ones you have watched.

I enjoy watching matches. With my schedule I, like a lot of people, catch the VODs as cannot purely watch live. Unfortunately I sometimes lose track of which ones I have watched. So it gets annoying when I realize I ended up watching the same match again when I catch up on some binge watching. And this impacts even more with the "Watch and Earn" missions where of course the same match is not going to count twice. Having to write down every match I have watched is not fun when I just want to enjoy the matches.

So please RIOT, we need a marker on the streams/VODs showing we have watched them, perhpas even to show this allready counted for a mission so does not count again. Would really help avoiding accidental repeats.
