Changing background images

Netrunner Netrunner Desktop 17.10

Hi,

I want to change three standard backgrounds to a custom one:
[list]
[]Desktop background
[]Lock screen background
[*]Login screen background
[/list]

Right clicking desktop brings up a menu for selecting Desktop background, and that works.

But how do I change the other two? Is there a working menu for selecting those, or do I have to manually create a “theme”?

Thanks

Lock screen background: System Settings - Display - Screen Locking - Wallpaper
Login screen background: System Settings - Startup & Shutdown - Login Screen (SDDM) - there is a button on the right side called Background
