title: Is possible to use Cortana for in-app voice commands?
body: <p>Is possible to use Cortana when application is running in Windows Universal Apps?
  My use-case is pretty simple - I need to handle situation, when user say: "Open report from {June 2015}" where {June 2015} is placeholder and can contain any date...
  I know how to do this when application isn't running and application needs to be launch; but I'm not sure if is possible to do this when app is running...</p>
