Access to Name of SubNode-Instance

The basis is a subnode name as “SubFunc” in Node-Red.
Now the subnode is instantiated and a name “DoSomething01” is assigned to this instance in the UI.
How can I access the assigned name of this instance in the subnode?

When i use node.name in the subnode i only get "SubFunc".

The usual way of expanding the msg in an additional function node beforehand is not a solution for me.

According to my research, the name of the instance is only saved in the Node-Red UI.

Is this correct or is there a way?
