Cabin crab handle

Hi folks,

This is my first post although I am lurking for the past two years! I have a 2008 2LT with 21K miles and so far I am a happy camper-no complaints. The only sort of a problem (wife always complaints) during turns or stops that she can not hold on a crab handle!! Has anybody found any after market solution? Any small suction grab handle I can mount on the passenger door glass? I Googled but I have found mostly the security ones for the seniors in the bathroom. Your help is appreciated. Happy New Year
