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?


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.
