How to use cached components when using Rasa as a server

As from method, components can be cached with implementing cache_key. It looks like caching is done by ComponentBuilder class.

There is a tutorial for caching components when using rasa from pyhton API, by passing the same ComponentBuilder instance to the Interpreter.load method.

But when using the REST API to load a model, a new ComponentBuilder instance is created by rasa each time a request is received so the caching does not work. Is there a way to make this work when using REST API?
