If [aMenuCell hasSubmenu] is true, [aMenuCell target] is the id
of the submenu.

You don't need to walk the itemlist if you have the MenuCell id.
Use getRow:andCol:ofCell: (Matrix) followed by
removeRowAt:andFree: (Matrix).  I haven't actually tried this,
but you may have to sizeToFit the matrix before sizeToFit on the
menu.
