Matches, let us pick what map we want to play

Can we update the match making. Is there a option to ban more maps. Or allow us to pick what map me want to play. I like match making as it matches people to your self lev or something if that how it work, but randomly generated map you get from matching, feel like it forced game content, let people choose what map they what to play, but keep how you match people the same elo or point. I just want the freedom of choosing what map I want to play with other on rank game rather then letting match making decide what to play.
