Section and Page Breaks in Reports
OK for others searching this is what I found works

 $sections = array ( 'mybreakcolumn' =&gt; array (
                  'title' =&gt; 'Rep Name',
                  'type' =&gt; 2,
                  'section' =&gt; 1,
                  'pageBreak' =&gt; 1,
                  ));

                  $this-&gt;assign('sections', $sections);


Where mybreakcolum is the full column name sent to the template
