Creating a 50/30/20 budget with new Category Groups

Quicken Classic Deluxe Version 7.9.0 Mac

I have expenses categorized into categories and sub-categories. I've read about Category Groups and being able to change them for reporting.

I'm wanting to create a 50/30/20 budget, and thought if I could create Category Groups to Needs, Wants, and Investing, and move the existing categories and sub-categories into those 3 Category Groups, I'd be able to clearly see spending for 50/30/20.

I see at Window > Categories I can make and change categories and sub-categories. Where do I create or change Category Groups?
