How to programatically change or set the Default Page

[Richard I]

Hi all
I want the user to be able to set which page in their NT application is the default or opening page
s_web._SitesQueue.Defaults.DefaultPage = 'IndexPage'
s_web._SitesQueue.Defaults.DefaultPage = 'LoginForm'

I note the setup happens in the INIT and presumably,  before session values are set.
Is there a way ?
Thanks

SET(Manage)
Access:Manage.Next()
IF MAN:Something = 1
    s_web._SitesQueue.Defaults.DefaultPage = 'IndexPage'   
ELSE
    s_web._SitesQueue.Defaults.DefaultPage = 'loginform' 
END
