OData Data Refresh - including custom Power Query formulas inclusing OData.Feed

We have a very similar request: We are extensively using Power BI's OData feature to retrieve data from Microsoft Dynamics NAV. Since a typical report needs to retrieve data from multiple data source it is time-consuming to change each OData.Feed () call when we are moving a report to another customer. We tried to build up the OData.Feed () from another query called ODataBasePath in order to create a single reference point where we can change the OData-connection. It could look like this in all queries: Source = OData.Feed(ODataBasePath & “ServiceName”) In Excel and Power BI Desktop this is working fine. However the scheduled refresh on PowerBI.com seems to be unable to handle this dynamic OData.Feed. It is giving this error message that the scheduled refresh is currently not available for this data source. It would be of great help for our standard reports.
