There's a workaround - add a main heading block (I'm using "* Page
Summaries" as an example here) and add something like this to the page
load/save hooks:

(defun chrismdp/planner-page-summaries-update ()
  (interactive)
  (save-excursion
    (save-restriction
      (when (planner-narrow-to-section "Page Summaries")
        (delete-region (point-min) (point-max))
          (insert "* Page Summaries\n\n"
                --- ADD YOUR CODE HERE --- "\n\n")))))

I've using a similar trick for agendas, which looks in the page for an
"Agendas" section and if found fills it with a list of all "Agenda"
prefixed plan pages with open tasks on them (I'll post that in a
seperate thread when I've polished it, as part of "How I do Gtd")

Cheers
Chris
