show tasks only for a desktop in taskbar

Hi List, I run Suse Linux-10.0,KDE-3.5.1 'a' , I have 4 desktops i.e Desktops numbered 1-4 in the panel , and say i want open 16 windows/apps , 4 per Desktop, the taskbar still shows all the 16 tasks, and i feel that the purpose of having multiple desktops is defeated , all the windows appear cluttered in taskbar when i choose any of the 4 . Is there a way in KDE to show tasks related to only a particular desktop in the taskbar,and not all of them Thanks Digz
