Multiple gnome sessions for 1 user in Gutsy

[Rashkae]

I want to create extra gnome sessions for 1 user.  All the documentation
I find on the net says there should be an Add button in the Session
Options tab of Session Manager.  This is also what I find if I click on
the help button on the Session Manager.   (Say that 10x fast)

However, in Gusty, when I open the Session properties and click on the
Session options tab, none of that is there.  All I have are a check mark
to Automatically save my session and a Save now button.
