A way to make Cesium Entities readonly?

Hey all,

I have looked around the forums and cesium API, but I could not find anything to make this possible. I want to make certain Cesium entities readonly. Specifically, users cannot edit any specific fields of an Entity once created. I need this to ensure certain entities stay constant once created. I have worked my way around this by creating an abstraction layer specifically focused on editing entities, but I was just wondering if there was a way to do it using the Cesium API.

I am currently using:
Google Chrome Version 49.0.2623.112
Windows 7


I don’t think there isn’t anything built into Cesium to handle this. Adding your own layer sounds like a good solution.
