I'm using a Contextual Filter Summary in an Attachment attached to a Page Display without inheriting arguments so that the Summary always shows. I would also like to show an "All" link at the top of the summary list as well, since I'm showing the list even when a contextual filter is applied. As far as I can tell there's no UI control for this, is there an ideal hook to use to inject an All option into the summary list?
Thanks!

For now I've simply overridden views-view-summary.tpl.php in my theme as views-view-summary--name--attachment.tpl.php, although I'd prefer a hook if there if one.
