Can we report people in Champ Select?

Title. :) Had to dodge 8 games this week because of premades supporting the people they were partied with in trolling(eg. someone says they got top when they joined late and precedes to instalock and their premade supports them and flames the person who actually got top) so I was wondering if I could actually report them(it doesn't seem like you can but then again my eyesight isn't exactly amazing...:P).
