How to have better description and examples for SDK generated by PyGen?

We are using Pygen to generate Python SDK for our Data Model. Pygen has given us good set of classes and methods which are really helpful. However, descriptions added in this generated SDK are very generic and not that useful. I think the only way to add descriptions and examples are manually doing changes to each classes and methods.

We are planning to use Pygen to create SDK and may generate SDK multiple times based on data model versions. If we put our own descriptions and examples manually then each time new SDK will generated we will loose the descriptions and examples.

Here, descriptions should be applied to all classes, methods, arguments etc.

I believe there should be way to create SDK with relevant descriptions and examples.

Please suggest what needs to be done.
