Disable option to ban pick-intent champions

Pick-intent is done before banning. It would be easy to implement a feature to disable the ability to ban teammates pick-intent champions. I would like to see this implemented.

The counter argument that I often hear is that an overpowered champion is better off being banned than left open for a teammate who is last pick in order to avoid the risk that the enemy will pick that champion. However, I see this feature used to troll teammates more often than not. There's also plenty of time to change pick-intent if players discuss the pick-ban situation and determine that a certain champion is better to ban than risk leaving open.
