'Fraid not.  The best I can think of offhand is:

<dtml-call "REQUEST.set('topdown', [])">
<dtml-call "REQUEST.set('loopdone', 0)">
<dtml-in PARENTS skip_unauthorized>
  <dtml-unless loopdone>
   <dtml-call "topdown.insert(0, _['sequence-item'])">
   <dtml-if "...last iteration...">
     <dtml-call "REQUEST.set('loopdone', 1)">
   </dtml-if>
  </dtml-unless>
</dtml-in>
