Compare Date Ranges Page

Google Analytics has a very nice feature that allows me to compare two date ranges. When you enable this feature, it overlays the data on the initial report loaded and makes it very easy to see how you are doing compared to selected period.
Achieving something like this seems very difficult in PBI (you can do things like same period last year or last month but ti requires a lot of effort and just is not very flexible).

I am suggesting this as a new page type as this would mean that the page would be smart enough to limit the availability of visuals that would work on such a page.
