applet sections in kicker

Hello, where can I configure how applets dock into the kicker bar? For every new applet kicker opens a new section (with devider and arrow). Existing applets, e.g kmix and klipper appear in a common section without devider. I would like to have applets (at least some of them like clock and logout) in just one section together with the kmix and klipper icon (with only one devider i.e between task bar and my section). Where can I configure that behaviour or do I have to change the .desktop files? If so. how? cu Stefan
