As a developer, I'd like to be able to change layer's source.

I'm using ol to show Bing Maps. I have different ol sources for Road, Aerial and AerialWithLabels imagery sets. I have one ol layer so I can maintain the correct position/index all the time. Switching the layers imagery works by changing the source in ol, but the change doesn't get synchronized to Cesium.
