bBrowser 3 groupcollumn

Hi all,

from bBrowser Help: "Both data columns and other group columns can be added to a group column. In this manner, complex groups can be created."

How can i add a GroupCollumn to another GroupCollumn?
Like this:

COMPLETE ADRESS

FULL NAME | PLACE OF RESIDENCE
-----------------------------------------------------------------------
FIRST NAME | LAST NAME |ADRESS | CITY | COUNTRY


TIA
