“Automatically add new top-level pages” Default

I'm looking for a way to set the default "Automatically add new top-level pages" to be checked when creating a new menu. I haven't been able to find anything on this - any help you could give me? Thanks!

<?php
add_action( 'wp_create_nav_menu', 'PREFIX_nav_menu_auto_add_by_default' );
function PREFIX_nav_menu_auto_add_by_default( $id ) {
    $options = (array) get_option( 'nav_menu_options' );
    if ( ! isset( $options['auto_add'] ) ) {
        $options['auto_add'] = array();
    }
    $options['auto_add'][] = $id;
    update_option( 'nav_menu_options', $options );
}
