How do I create a batch table?

It is said, that a batch table contains per-feature application-specific properties in a tile. I create my glb/b3dm-Models of a tile with Blender and the 3d-tiles-tools. The created b3dm-Files have no features and no batch table.
Is there a tool to add a batch table to my model file?

When you upload a dataset to Cesium ion, it’ll typically collect per-feature information and add it to the batch table. For point clouds for example it puts the Classification and Intensity values. I don’t think it puts anything for glTF models. We have an issue open here collecting feedback about adding an option to control this when uploading data:

Feel free to chime in there!
