How can I select MULTIPLE dynamic landscapes and have them randomly change every so many minutes or hours?

Running Mac OS Sonoma 14.3.1, and use the built-in Landscape wallpapers. Would like to select multiple landscape images from the Wallpaper Settings page, and then randomly rotate images every so many minutes or hours, but so far cannot find any way to select multiple Landscape images in Settings, let alone how to tell it to randomly rotate those images in a given timeframe. Is there any way to do this,
