Ranked Queue

When you pick what role you wanna play is there any way that when you choose the "Fill" option that you can make it to where you can pick a role that you don't wanna fill? You can pick two different roles before going into queue. So the way this could work is for Option 1 the player picks "Fill" and then option 2 would be picking a role that they dont want to play. If that player doesn't mind playing all roles then they can just pick Fill again. I myself don't mind filling however the fill button is just a 2nd support button.
