Changing wallpaper on all screens

[Ryan O46]

Hey Everyone,

I recently downloaded a pretty cool theme called 'The Chic', the all black layout and app icons are nice but the wallpaper is of some goofy car. Fortunately I was able to go into Settings and change the Home Screen, Lock Screen, and the Text Message window screen to a solid black. However there are some screens that still have the stock theme wallpaper.

Any idea on how to change the wallpaper on additional screens such as settings, the general text interface (not the screen for an individual text, ect...

Thanks!
