Hello,

I am trying to obtain some "multi-level" configuration system and to achieve this I would like to use a configuration node inside another type of configuration node.  
Is there any chance to obtain this?

Yes, that is possible. For example, the `mqtt-broker` config node makes use of the `tls` config node.

There is little difference in a config node referencing another config node as to how it works with a regular flow node using a config node.
