Dynamic Description > File Size?

Hi everyone, I’ve run into a problem with excessive CZML file sizes (1GB+) due to dynamic descriptions with complex formatting. Is there a way to use a description “template” (static) and only update numbers within that for each time step?

Context: I’m using CesiumJS for visualization of satellite network architectures simulated in python and exported using the czml3 lib. The description box for each object (satellite, ground station, etc.) is dynamic and updates with scenario time about once a minute (image below). The viewer loads this from an external CZML file via JS promise, but 90% of the resulting CZML file size is the repeated HTML content of the description which is mostly static except for the number values.
