Dynamically update node number

[Awildmann]

I'm currently trying to change the positioning of the elements in the tree by also updating the node number of each entry. Say moving 1.1.2 over 1.1.1 so it becomes the new 1.1.1?

The problem is, the numbers don't get updated unless they're brought into a different parent node. Is there already a functionality that changes the nodes when their position changes within the same node? If no, is there a way to make this work?
