YES. The single-category issue is a continual annoyance for many gamers who stream multiple games in a single stream, which can happen for a multitude of reasons. If I play three games in a single stream, I should be able to tag all three, on the VOD at least. If I'm searching for a particular game, some other streamer deserves to turn up in my search even if they only played it for part of their stream and chose to tag one of the other games they played in that broadcast.
