Generate more than one Report in one pbix file using the same Data and Relationships with Power BI Desktop

RE: Generate more than one Report in one pbix file using the same Data and Relationships with Power BI Desktop

This feature is also helpful to develop reports for both desktop and mobile devices.
Now, I have to duplicate the pbix file and develop a report for desktop and a report for mobile. Any time I have to apply a modification to datasets, queries or measures, I have to manually repicate that on both pbix files.
With such a feature, I can reuse datasers and measures and create different pages, one set for desktop and one set for mobile.

A simpler feature could be to show and hide each page based on the device type of the user who is vieweing the report.
