When you use the Model Advisor, you can load any configuration. Once you load a configuration, you can set it so that the Model Advisor use that configuration every time you open the Model Advisor.
Open the Model Advisor.
Select Settings > Load Configuration.
In the Open dialog box, navigate to and select the configuration file that you want to edit.
Simulink® reloads the Model Advisor using the new configuration.
Optionally, when the Model Advisor opens, set the current configuration as the default by selecting File > Set Current Configuration as Default.
