Changing the rotation rate of the Globe/Ellipses for various central bodies in cesium

I’ve been doing some really fun work using cesium to display trajectories generated by GMAT at different planets.

I can easily replace the Earth with a Mars sized ellipsoid using a topography map of mars [Here]( Hello World - Cesium Sandcastle)

However, this globe still rotates at 1 revolution per day with respect to the inertial frame. Any advice on how to change the rotation rate of a globe with respect to an inertial frame?
