Create drop-down row grouping as an option in the Output Tool

[andrewdnolan]

It would be neat to add a feature to the Output tool to allow grouping by rows, with all the data related to the group column viewable under a drop-down of the selected field. 

I've heard that this is possible with a power pivot but would be a nice feature in Alteryx.

Ex. A listing of all customers in a specific city -> Group by the "Neighborhood" column, the output should be a list of all neighborhoods in the city, with an option to drop down on each neighborhood to see its residents and their relevant data. 

Thanks!
