テーマのアクティブ化でカスタムサイドバーにカスタムウィジットを挿入する方法

私はカスタムウィジェットを作成しました、そして私はそれを私がテーマ活性化で欲しかったどんなサイドバーにでも挿入したいです。出来ますか？

ところで、これが私のサイドバーに使用したコードです。

function awesome_register_sidebars() {
    register_sidebar(
        array(
            'id' => 'sidebar-footer-1',
            'name' => __( 'Footer Nav  Links 1', 'Awesome' ),
            'description' => __( 'A short description of the sidebar.', 'Awesome' ),
            'before_widget' => '<div class="footer-link">',
            'after_widget' => '</div>',
            'before_title' => '<h3 class="footer-link-head">',
            'after_title' => '</h3>'
                ));
register_sidebar(
        array(
            'id' => 'sidebar-footer-2',
            'name' => __( 'Footer Nav Links 2', 'Awesome' ),
            'description' => __( 'A short description of the sidebar.', 'Awesome' ),
            'before_widget' => '<div class="footer-link">',
            'after_widget' => '</div>',
            'before_title' => '<h3 class="footer-link-head">',
            'after_title' => '</h3>'
                ));
register_sidebar(
        array(
            'id' => 'sidebar-footer-3',
            'name' => __( 'Footer Nav  Links 3', 'Awesome' ),
            'description' => __( 'A short description of the sidebar.', 'Awesome' ),
            'before_widget' => '<div class="footer-link">',
            'after_widget' => '</div>',
            'before_title' => '<h3 class="footer-link-head">',
            'after_title' => '</h3>'
                ));
}
add_action( 'widgets_init', 'awesome_register_sidebars' );

そして、これが私がウィジェットに使用したコードです：
