Views 3: template suggestion file for header/footer parts? In Views 3, is there any type of template suggestion for header and footer parts of a view?

I know I can paste Full HTML into Global Header and Footer fields, but - as I have the main part themed in a tpl file - I'd also find it more comfortable to have the header/footer parts laid out in an external text file.
There's no template that I know about, but nothing can stop you from overriding the header and footer values in a view's general template like views-view.tpl.php, or even include a separate file instead of outputing the variable directly.
