Please add role preference selection to Blind Pick

I am getting udderly sick of the concept of calling the lane you want in Blind pick. it wastes time and seems to end up in people fighting over who's text appeared first in the chat window. You have role selection in draft mode so I don't see why this cannot be added to blind pick also. It would not add to the que time in my opinion and would eliminate the race to type something when I only get 1 minute to select my champ and get my runes in order.
