powerapps – How to navigate to another record in a data source while testing in Power Apps Studio?

When I am developing a Power Apps application in the Power Apps Studio I seem to be always stuck developing/testing with the first record loaded from a data source (in this case, the first item in a SharePoint list or library). This is sometimes fine, but occasionally I would like to move to a different record to test how the Power App behaves with different rules, etc.

Is there a way to quickly change to another record in the Power Apps Studio purely for testing and development purposes, without actually changing the way the application loads records at runtime?
