カテゴリー・リストのアンカーリンク

お世話になります。
WordPress・PHP初心者です。
カテゴリー名をクリックした時にアンカーリンクで指定の場所へ飛ばしたいと考えています。
現在、下記のソースでカテゴリーリストを表示しています。
——————————–
<div class=”sidebar_box”>
<ul class=”cat”>
<?php wp_list_categories(‘title_li=’); ?></div>
——————————–この状態で、カテゴリーの1つをクリックすると、ページの一番上から表示され、
URLでは「http://○○.com/category/○○/」と表示をされます
ヘッダがとても長いため、これを、カテゴリー名をクリックした時に指定の場所へ飛ばすアンカーリンクを設置したいと考えています。
URLでは「http://○○.com/category/○○/#koko」と表示したいです。そこで、
wp-includesの中にある、【category-template.php】の中で「#koko」を追加することが出来ると思うのですが、また記述の方法など教えていただけますでしょうか。<?php /** * Category Template Tags and API. * * @package WordPress * @subpackage Template */ /** * Retrieve category link URL. * * @since 1.0.0 * @see get_term_link() * * @param int|object $category Category ID or object. * @return string Link on success, empty string if category does not exist. */ function get_category_link( $category ) { if ( ! is_object( $category ) ) $category = (int) $category; $category = get_term_link( $category, 'category' ); if ( is_wp_error( $category ) ) return ''; return $category; } /** * Retrieve category parents with separator. * * @since 1.2.0 * * @param int $id Category ID. * @param bool $link Optional, default is false.
