Override for products_all page?

I've needed to modify the query for the products_all page to accommodate a re-purposing of it...

But I can't seem to figure out the override structure (if one exists) for modules/pages/products_all/header_php.php ... I've tried creating a new folder for my custom template under every level there, but the changes don't show.

Is this a change I can preserve or is it something I'm just going to have to note for future upgrades?

Any answers are appreciated. :)

there is no over rides available for /modules/pages

I maintain a notebook/file on an install and for these non-overrideable edits this is how I handle it: Take your modules/pages/products_all/header_php.php file and after making a local copy to edit - rename the one on the server to modules/pages/products_all/header_php.orig then upload the edited file to replace it.

Using this as the acid test and the notes on what was/where these exist - prior to an upgrade these can be preserved and later diff'd for possible updates that the upgrade might have before

Thanks for the quick answers! I already have a few other files I've had to take note of, so I'll just add this to the list. :)
