Mute signals and pings from selected player

Some players miss use pings and alerts in game in a confusing and irritating way, and some players when you tell them to stop spamming they will do it more and more just to make you angry . I am a type of person who get confused by that spam , i always tell them one signal is enough but they use like 20 signals at one fight . I hope Riot will make an option to mute a player's pings and alerts ( at least the sound only ) same like when you can mute his chat .
