so yes it is, is a curstom containment, which is a completely different thing 
than a view (which is a shell feature and can't be changed at all by design)

it is not possible to create a different panel view neither change the panel 
settings view, nor the sizing policies.

What you can do is to add a custom action to the context menu, which will 
create a new dialog window in which you can put the settings controls you need
