Game type in lobby

Just throwing it out there ,(unsure if anyone had thought of it yet), but I think a good idea for creating a party is the option to change the game mode while in a party. Say you have played a 5v5; you hit play again and you've had a change of heart, and would like to play a ranked or maybe an ARAM. A drop down menu label "Gametype would be much more practical than cancelling the lobby and making a new one. Don't go too hard on me guys.. I don't follow boards so I don't know what's been posted.. Thanks!
