This is probably quite specific, but I am creating a drag and drop system where what is NOT dragged needs to be reactive to where the dragged object is. I can’t show you my real wireframes but here’s a representation that hopefully is clear enough: 

What I am “doing” is dragging the purple circle. I need to get it over to the first place (where the red circle is). When dragging, once the purple circle is dragged near the second position but NOT dropped, the yellow circle should react and move to the third position.
Then I want to continue dragging to the first. Ideally this is of course one smooth motion.
Currently though if I have the second frame and third, I have the interaction on the purple circle from the first to second on “On Drag”. But if I do the same for frame 2 to 3, I need to reclick the purple circle to start dragging again.

Does anyone know a workaround for this?
