Combine several terrain providers


I am working on a research project for my Ph.D. which involves the use of seafloor terrain (Bathymetry).
I am working in Cesium ION, where I created several assets - two of them are bathymetric layer.

  • assets 203206 is a high resolution (1m cell) dataset with a small extend
  • assets 203249 has a coarser resolution (5m) but has a larger extent.
    I wonder if (and how) I can hierarchically render those two terrains - in particular, I’d like to render the hi-resolution asset on top of the coarser one … is that possible?

There was a similar question and the suggestion was to merge the terrain when you upload them to ion:
