Code to separate fields for custom title

Hello, thank you for best checkout plugin.

But I need one option. I need “separate” shipping method field by “free custom field” or free space for custom title for local pickups like:

Shipping method

• DHL

• American Express

Local Pickups

• city one
• city two
• city three

If I use this code: I add text: “Osobní odběr (zdravotnické pot?eby EMPOLAS)” only to field with delivery method. I need add this up to local delivery methods.

add_action(‘woocommerce_after_shipping_rate’, ‘woocommerce_after_shipping_rate_callback’, 10, 1);
if(!function_exists(‘woocommerce_after_shipping_rate_callback’)) {
function woocommerce_after_shipping_rate_callback($method) {
if(‘toret_tcp_doruky’ === $method->id){
echo ‘

Osobní odběr (zdravotnické pot?eby EMPOLAS)’;
}
}
}

Thank you for your help
