You might want to check out LaunchCenter Pro:
It’s like speed dial for anything you do with your iPhone or iPod Touch. Create one-tap shortcuts straight to the feature you need
inside of your apps.
Message a loved one, search Yelp for the nearest coffee shop, jump
straight to the camera in Instagram, all with just a flick of your
thumb. Create shortcuts for email, Safari, phone or FaceTime calls,
Google searches, and more. If you do it on your phone constantly,
Launch Center Pro will make it easier and faster.

I haven't tried it, personally but the description above seems to indicate it will work. You might also follow the recent news that some of the features of LaunchCenter pro are being disabled at Apple's request by the developer.
