When entering the Catalog Page, the App will fetch all the POCs related to contentVersion. A default content version named “main” will be used as the default data set for all POCs. When data is fetched for the specific custom content version, the backend server will first fetch all the data from the “main” content version, then fetch data from the specified custom content version and merge it. That approach will allow a custom website to rewrite only to edit and leave the rest of the state as they are in those POCs that we would like to use in the same “main” content version at the moment of the time.
