Option to Reject Own Team Ban of Declared Champ

Why is there not an option to override a team troll ban of a champ that you have declared but not yet picked in champion select? With the advent of autofill, it is a recurring strategy that support autofill players ban a champion that a teammate has declared in hopes that it will make them dodge the lobby so that they can get out of the force support role.

There needs to be an option to counter this obvious troll force-dodge strategy. It is hard enough to play what you want in this game anymore. Now when you actually get the role you want, you have to deal with this added bs.
