Dataflow REST API that retrieves only the data sources actually associated with the given dataflow

We would like to have a Dataflow REST API that retrieves only the data sources actually associated with the given dataflow.

With the current API, [Dataflow - Get Dataflow Data Sources], when the same connection information is defined across multiple gateways, all matching data sources appear as candidates—even if only one is actually used in the dataflow.
