Hello again,
From what I know there is none. For me I just go in Groupy 2 setting and set it up as how I want it to work. Adjust the setting as I goes along. The very first setting I will set up usually on the Grouping setting and Grouping Rules. The rest, for me, are more on cosmetic.
Just my two cents.
Thank you,
