I have a project in aws sitewise that contains some thousands of assets and properties.

I want to update some hundreds of properties in different assets, for example I want to make them to allow to notify to IoT Core using the MQTT Notification status.

I wan think in these steps:

1. Download the json that reflects the full configuartion of the models, assets, properties, metrics transforms, etc. I dont know yet how to do that.
2. Apply the changes in the places I want - in this case set "propertyNotificationState": "ENABLED", for each transform or properties that I want to change
3. Update the changes. May uploading the JSNO or creating a script to perform that changes.

What is the appropriate approach to do that? IS there any native function or api endpoint for that?
