Ability to limit width of play area

My play area is about 8-9' wide, with a couch on the left and a chair on the right. Sometimes the buttons in the Fitness app are on the couch or on the chair. Same with kicking the soccer ball in the Family Fitness app... it shoots the ball too far left or right and I can't kick it. And some games in the Arcade app as well. It would be great to add an overall setting on the unit to set a "playable area" on the left and right sides... like a way to make the camera a little less wide angle. Ideally it would be a system setting that would affect all the games.
