Conditional Formatting on Page Background under Visualization's Format Settings

Frankly, I love the 'Jugaad' and 'hack' behind your solution.  And i use the same idea most of the time.

However, the reason behind my posting about a topic on the PAGE background, was to have that function added to the Power BI desktop as well. If they have given some page level abilities to the users they need to make it more formattable and add more features to it like Conditional formatting based on rules , or setting a wallpaper conditionally. Or changing the font color of the entire page according to the report page/tab rules. 

While setting shapes and visuals to format conditionally and sizing them to be equal to the page would do the trick but that's just a cover up and not the actual solution that we want to see from Microsoft.
