Using this to update page wallpaper?

Hi there,

Thanks for this integration! I currently have this line in every section. I wonder if this integration lets us to randomize the wallpaper??

```
    background:
      opacity: 50
      alignment: center
      size: cover
      repeat: no-repeat
      attachment: fixed
      image:
        media_content_id: /local/wallpapers/Green - Landscape.webp
```
