Add multiple images in theme settings with a single element

Hi everyone,

I would like to be able to add multiple images via the same element in theme settings, but I can’t figure out if this is possible.

Currently, I can add a single image with this setting:

# theme.ini
elements.img.name = "img"
elements.img.options.label = "Image"
elements.img.type = "Omeka\Form\Element\Asset"

Is there a specific element type or another solution for adding multiple images?
