You need to have a plugin (or add this at the bottom of a plugin) to eval the template to use (this uses a template_hook):
PHP Code:
eval('$template_hook[template_hook_name_here] .= " ' . fetch_template('your_template') . '";');
or without a template_hook:
PHP Code:
eval('$sponsor = "' . fetch_template('your_template') . '";');
And, you would select your product name when you edit your template and then it will export with it. You need to be in debug mode to do this.
