[Feature Request] Change wallpaper on Login/Startup

[BrodyB]

I've only seen this feature on macOS and nowhere else.

The Issue

When setting the user's wallpaper to a directory of images, the only option Pop!_OS 22.04 (and every other Ubuntu-derivative) has for cycling the next wallpaper is via a timer. After the timer is up, the wallpaper is changed. But what if I want to set other triggers for a wallpaper to change?

Request

I'd really like an option in the Wallpapers settings to cycle to a new wallpaper on Login/Startup, so when I turn my computer on, I'm greeted with the "wallpaper of the day," so to speak. Additional settings could be added in, such as On Wake from Suspend. In these cases, the user wouldn't see the change happen, the wallpaper would be chosen and loaded before the desktop environment is displayed.
