Free form Drag and Drop with limited space

Hi all,

I'm currently working on a free form drag and drop question. There's very limited space on the slide, that's why I put one drag element on each drop area. This is also necessary because the answers need to be shuffled, and I'd only have enough free space to stack them at the side, but this would interfere with the shuffling option for the answers.

I've also activated the setting, that only one drop element per drop area is allowed.

Now here's the issue:
I imagined that this setup would be enough to allow the learner to swap two drop elements with each other, e.g. element1 is on droparea1 and element2 is on droparea2 and when I move element1 to droparea2 element2 is moved to droparea1.
But this only seems to work, when both elements were moved at least once. So not in the initial state, the slide shows up.

How can I achieve the swapping of drop elements even if the elements weren't moved before? Or can I add a trigger which causes all elements to move when the timeline starts, so they get the correct state?

If this is not possible, is there any other way to have shuffled answers within my very limited space?
