Esports Website Request

Background about how I watch LCS: So I tend to watch the League pro games after they air, partially due to my schedule. I prefer to watch the VOD's anyway compared to live. The only Issue with watching the VOD's is I can't remember which games I have already watched. And I don't want to skip ahead and "spoil" the game.

I mainly watch NA, but I occasionally watch EU, and the other regions. I would probably watch more if I knew which games I have already viewed. For the Korean/Chinese games It isn't as bad because I tend not watch the out of game talk shows. I know if I have seen the game before if the youtube like starts towards the end. However for the NA and EU games I thoroughly enjoy watching those programs in NA and EU, so this strategy doesn't work.

Request: Since I am logged in to the League site, could you implement a tracker which remembers which VODS/games I have already watched?

I know this is a very first worldly problem, but what are others thoughts on this?
