Changing order of drumset icons in Musescore 3?

I seem to recall that Musescore 2 allowed the drumset shortcut icons to be reordered by click-an-drop. That feature is absent now in Musescore 3. There seem to be no way to reorder the shortcuts even though I have changed their key shortcuts in the "edit drumse" dialogue box. Any idea of how to reorder the sequence of icons displayed at underneath the score.
