Default [Q] Disable Proximity Sensor

Not sure if this is the right place for this, I tried to post on the Cataclysm ROM thread, but can't so I was redirected here.

My phone took a little tumble today and the top left corner took the hardest hit, making the prox. sensor always detect something near. This is a problem in calls so I want to disable it in calls.

My solution was to get a custom rom with that setting built in, so I downloaded Cataclysm build from 12/12/2013. According to the changelog, a miscelaneous setting was added on April 19, 2013 allowing for this. But when I look through the miscellaneous settings, I don't see that feature.

Were some features removed? Or am I just being stupid and not seeing how to do it.
