Collab viewer explode view blueprint edit

Hi,

I found the explode view blueprint and it works great. I even edit it to move bodies only one by one.
The blueprint has start position and end position. I was wondering, can I add one more array, so the body has three points where do move, like path (first it goes to second position and then to the last position). How can I edit the blueprint to add one more button ( to set middle point) and one more array for the middle points.
