Yes, have a look in /etc/e-smith/web/functions. Here you will find the perl code that create the server manager panels. Open one of the function sin pico and have a look in the header for the file for a line that looks like this:
# heading : Collaboration
# description : Groups
# navigation : 3000 3200
Play around with the navigation numbers. The first number is used to define the major group and the second the order within that group.
