There is the session-leader window.  Not designed for this, but could do 
the job.  On the other hand, creating a new selection-holding window is 
not much job.  For multidisplay you actually need one window per 
display, so the session leader isn't really appropriate.  That is 
display as in X11 Display*, not display as in multiscreen.
