Moving specific instances

Hello all :)

I am working on an interaction where you can add and remove elements to a sandwich.

Ex: +BURGER button adds a burger to the sandwich. Same thing with the other ingredients.

In order to remove, it is done by draggin it out of the sandwich pile. The user should be able to drag any item of their choice.

Let's say I have a pile of 5 burgers, and I want to remove the 2nd from bottom to top.

QUESTION: how do I make ONLY the burgers (and any other ingredientes) above it to move down?

Here's a screenshot:

Thank you all in advance :)

You can make a hierarchy, adding each new sandwich layer as a child to the previous layer. Like a chain.

Then when you drag any of them, all objects above (all children) will be dragged too.
