Haptic vibration while getting a call - possible?

I would love to get a haptic vibration while getting a call.
Asking this, because since I have the 5.0, I have missed so many calls.
Is there such a functionality somewhere in the app?
If not, where to request that feature?

My job requires responding to time sensitive calls. I would like to know if there is a call when my phone is not in my pockets.
