Can Data Sources Be Appended and Updated Through a Data Source Refresh?

The appended data source will be updated only after each individual data source has been successfully refreshed. For instance, if an appended data source is created using data source 1 and data source 2, it will not have a separate refresh option. Instead, the data in the appended data source will be updated whenever either data source 1 or data source 2 is refreshed successfully.
