Report 'Personalization' Feature Suggestion

Hello all,

I recently discovered the 'Personalization' feature for report viewers. This is an extremely powerful feature and allows end-users to practically create their own reports, even in an embedded environment. 

Two things come to mind though that would increase this feature's utility exponentially.

1. Add the ability to rename columns added via personalization feature. 

2. Add the ability to modify chart formatting options. 

With the current capabilities, column names are static and cannot be changed unless the dataset itself is modified (which isn't always an option.) If some columns aren't named very specifically, this can quickly cause confusion. For example, if you have a cars table and a trucks table that contain data for top speeds, you may just see 2 columns named 'Speed' without context to which table these belong. Being able to rename these, for example "Truck Speed", would be extremely useful. I have an example below of what a 'personalization' pane looks like with vague columns for Truck, Car, and Motorcycle names/manufacturers.

The power to customize visual formatting speaks for itself. Titles, colors, fonts, etc.
