Allow select app to route through VyprVPN. For example you only allow Facebook and Email to use VyprVPN, instead of all the apps.
You can select which apps can route through VyprVPN instead of all apps.

I am not so sure the answer is satisfactory, once you have an app connected through VPN I guess you cannot exclude the others to route without VPN, that would be very useful!
What VyprVPN allows is "Use VPN" or "Auto connection", no exclude option for the apps.
