New wallpaper editor for iphone

Why after the last update, which allows you to create a lot of new wallpapers for your phone, it became impossible to edit already created wallpapers? I already have a wallpaper with the photo that I like, and I want to change the design of the clock on it or add widgets, I click the "customize" button, and they offer me to create new wallpapers and customize them already. This is problematic for me, because I no longer have the photo that is on the wallpaper, so I can't create a new wallpaper, but I still want to change something in it. I hope that you will add this feature.
