Try doing only localized grouping with variables (solution below). You'll see that I am only grouping the projects on the collection of records for each customer.

I can get the listing of Unique customers
Customer 1 Project 1 Project 2 Project 1
Customer 2 Project 1 Project 1
However I'm unsure as to how to only list the unique Projects within these listings. I've checked the archives and Dawsons (but couldn't find anything obvious).
Try doing only localized grouping with variables (solution below). You'll see that I am only grouping the projects on the collection of records for each customer.
