The addAdditionalLayerOption layer option is specific to the Imagery Layers Manipulation demo and is not part of the Cesium API.
Can you explain in more detail what exactly you are trying to do?
I am working on map application which is very similar as Imagery Layers Manipulation demo where you can display and toggle between different layers. But what I need is to display two different layers with a single click.

You need to handle that manually in your application by keeping track of the groups of layers you want to toggle together and managing it yourself.
