eliz15 on "[Theme: Hueman] how to customize alx_pre_get_posts action ?"

Hi,

I would like to know how to customize or change this action which permits to exclude the featured post :

/*  Include or exclude featured articles in loop
/* ------------------------------------ */
if ( ! function_exists( 'alx_pre_get_posts' ) ) {

	function alx_pre_get_posts( $query ) {
		// Are we on main query ?
		if ( !$query->is_main_query() ) return;
		if ( $query->is_home() ) {

			// Featured posts enabled
			if ( ot_get_option('featured-posts-count') != '0' ) {
				// Get featured post ids
				$featured_post_ids = alx_get_featured_post_ids();
				// Exclude posts
				if ( $featured_post_ids && !ot_get_option('featured-posts-include') )
					$query->set('post__not_in', $featured_post_ids);
			}
		}
	}

}
add_action( 'pre_get_posts', 'alx_pre_get_posts' );

My problem is that it deals only with the main query, and I would like it to work for some custom queries (created on my homepage). I read that the pre_get_posts method can be only used for the main query, so is there any other solution to do that for a custom query ?
