Can we have a post-game chat toxic word/phrase filter?

I am not talking here about something as widespread as what you see on, say some of the competitors' games, but it would be nice, after a bad game (filled with disconnects, players pinging their high ms rates, trolls, players saying "ima afk", etc.), if we could have an optional player-toggled filter on post-game chat that would detect keywords and remove the potentially loaded toxic elements of post game chat: "gg ez", "ez", "xxx sucks", "inting", etc.

Nothing gets me so discouraged from hitting the "play again" button than that situation when you get a garbage filled game and then the opposing player (or even a teammate) says one of those ill-considered regular toxic phrases that just triggers you.

Or would Riot allow a third party to release such a plug-in for the game?

Either way: PLEASE?
