phone mount that works with a wallet style case on my GS4

I have a 2013 Prius and Samsung GS4. I keep the phone in a wallet style case*. I really like that type of case because the wallet style folds in front of the screen and it protects the screen and also gives a lot of protection if it falls on the ground. I'd like to buy a car dashboard mount that can hold the phone in that type of case. All the holders that I see advertised seem to be for standard cases and the holders grip the case from the long sides. That won't work for a wallet case. Anybody have any suggestions?

*you can search for wallet style phone cases on amazon if you don't know what that looks like.
