Visualizing subterranean data in Ion

Hi all, I am trying to visualize subterranean data in Ion. I have uploaded the data and can see it above ground, but when I set the data below ground I cannot seem to pan underneath the base terrain.
Is there a way to visualize subterranean data (data I have placed below the ground plane) in Ion or do I have to do this through Cesium JS?
The JS tutorials seem very straight forward so I know it can be done but visualizing in Ion might be useful for Stories.
Cheers.

Welcome to the Cesium community @operatormapping

If I understand correctly you are looking for a way to use underground data in Cesium Stories. At this time Cesium Stories does not offer a way to adjust the display of the globe. This may be a feature we add in the future and your feedback helps us prioritize what to work on next.

To view the data you could create a sandcastle with the asset. Here is an example of displaying underground data. However this does require editing CesiumJS code.
