Hi! Before kedro 0.18.0 I was achieving it with the register_config_loader hook because all the params passed through the command line were available in the extra_params. I would also be interested in knowing what is the best practice in the latest version. What I was thinking it may work is providing your custom class for the TemplateConfigLoader intercepting the extra parameters (runtime_params) , updating the global dict and returning the tamplate config loader with the updated global_dict.
