当然可以。首先创建提要as per codex:
function anotherfeed_init(){
add_feed(\'anotherfeed\');
}
add_action(\'init\', \'anotherfeed_init\');
现在，
change the post count 对于此特定提要：
function anotherfeed_post_count( $query ) {
if( $query->is_main_query() && is_feed(\'anotherfeed\') )
$query->set( \'posts_per_rss\', 30 );
}
add_action( \'pre_get_posts\', \'anotherfeed_post_count\' );
