Why don't companies like otterbox make cases with stylus and holder?

It seems this would be a no brainer to me.
Plenty of people like using a stylus with there phones and for a blue collar person like me, a rugged case with stylus holder would be a huge convenience for me. Also, it would help in the winter since I would not have to remove my gloves to use the phone.

Come on Otterbox, get with it.
