This request is a way to change the template folder in API, something like this:
$ca->setTemplate( 'my-new-template-file' , 'my-new-template-folder' );
Sometimes we need to create landing pages, or another way to show the products. And we want a clean template, without to many information at header and footer.
If this implemented we could have a template for each kind of products o advirtesiment , and stop using smarttemplate conditions at header and footer.
