Excel 2016 version
Allow Excel 2016 to run the latest version of Power Query. You can do this in 2010 and 2016 using the Power Query plugin. I recently updated to Excel 2016 and seems the Get Data Power Query is a few months behind on features and performance.

Drill Down Functionality
Drill Down Functionality : While drill downing user dont know about value of upper slice (from where he\she came), PLease add top legend that display value like Total Sales-->2015-->July-->India(Country). SO user can know about top value from where he came by doing drill down.
