Why is there no role selection for Blind Pick

Is there a reason that only draft pick and ranked give the option to choose your primary and secondary roles? Why doesn't blind pick have this option? I have seen complaints far and wide about insta-lockers, to people who dodge because they didn't get their desired role. Are there reasons that are not as obvious to why the role selection option is not available for blind pick. Another thing, why is there no way to report players during champ select? When people are rude, or say unspeakable things. We can not report them, instead we have to play a whole game with that player/players and then report them at the end. Maybe I am just ignorant to the ways of how Riot chooses to manage their player traffic, but I think at minimum the role selection for blind pick would be much appreciated by many. Please vote in the poll. Thank you for your time.
