Accessing parameters of nested parameterized objects when displaying in panel

Hi @JonathanMair,

What about something like this from @fdorssers whom made some progress, sounds similar to what you may be looking for though not certain; came across it searching for child classes

How do you pass a parameter object (from param) to a child class and listen to changes there, and propagate the UI changes back up - Panel - HoloViz Discourse

Thanks, Carl.
