Brilliant as always, Eric. :)
I wanted to wait and confirm that the order was correct before offering a
recursive macro, since the TOC macro does allow customizing the sorting for
different branches.
Given your code, a button could look something like this:
<$button>export report
<$wikify name="export-filter" text=<<toc-list here:"Contents">> >
<$action-sendmessage $message="tm-download-file"
$param="$:/core/templates/exporters/StaticRiver" exportFilter=<
<export-filter>> filename="report.html">>/>
</$wikify>
</$button>
