Custom Template Location

Hi,

unfortunately, i can’t use the template location in my theme, so i need to set up a custom template location.
I need this mostly for the emails.

I tried to do this with the “woocommerce_gzd_template_path” filter but had no success with the code below.
Is there another way how to do this? For the moment i had to change the main woocommerce-germanized template files, so for now i cant update the plugin, which is not optimal.

function filter_woocommerce_gzd_template_path( $woocommerce_germanized ) {
	
	$newtpl = str_replace( 'woocommerce-germanized/templates', basename( POXYB_DIR ) . '/woocommerce', $woocommerce_germanized );
    
    if ( file_exists( $newtpl ) )
        return $newtpl;
 
    return $woocommerce_germanized;
}
add_filter( 'woocommerce_gzd_template_path', 'filter_woocommerce_gzd_template_path', 10, 1 );
