Allow dragging multiple elements into an @exported array field to add them at once

[Kartopod]

Dragging multiple elements onto the add element button (Or maybe the array field itself, or both) should add all the elements to the array at once. This would make adding elements easier. At the moment you would have to manually drag every single element one by one.

I've instinctually tried this in the past and was left a bit disappointed, so it would definitely be nice to have.

I think I've seem a proposal for something similar recently, but I can´t find it, although I found #6862 that asks for the ability to drag and drop single elements.
