break (curve) apart with multiple entites selected

I want to know why CorelDraw won't let me select several curves at a time and break them apart simultaneously.  When I select more than one (by marquee or shift key) it greys out the "break apart" command, and Control-K won't work either.  I did find a work-around macro in an old post, but I don't understand why the CorelDraw programmers turn off the break-apart command for multiple selections.  Anyone have some insight on this?  What is the easiest work-around?
