[tde-users] Which desktop?

Is there a way, while starting a program, to tell it which desktop to appear on (before it opens its window)? I looked at the various Window-specific settings (right-click the mini-icon in the menu bar), and there's lots of things that can be set there, but not the desktop. I also looked at kdcop for several kinds of windows, but if there's something in there, I can't recognize it.
