It would be great to have an option to select and change the dataset of a Dynamics F&O connector on an "app level" in PowerApps Canvas. This would update the dataset of each/selected D365 F&O entities connected previously to the app.
This way, when developing and testing an app we could use different "target" environments, thus we would not create eg.: trash data in UAT environments when trying to develop a function that updates entities in F&O.
Also, app deployment would be easier, as after developing and testing an app, releasing it to production would only need to change the "master" dataset and not remove and re-add the connectors pointing to the production F&O environment manually.
