Nemesis Indicator

I was wondering if we could create a "Nemesis Indicator" as a way to get the game fueled up. My friend and I get into random matches and it gets competitive. But, he's on the enemy team and I forget where I know him from. Like a side note to who. Although this can be used to label people for example. "Coyot92 "Nemesis": That noob who outplayed you.""
