Reporting players after statistics screen

I sometimes have to "skip waiting for stats" after a game when the screen just won't load. This prevents me from reporting/honoring players who I really wanted to report/honor. I recently played a game where one of my teammates was playing with extreme negative behavior, yet I couldn't report them afterwards because I had to skip the stats screen. Is there any way to report a player once that screen is closed? If not, has the possibility of reporting someone you recently played with been considered by Riot?

tl;dr I needed to report someone but I couldn't. What do?
