How to calculate the price in the delivery processor based on the properties of the order?

Question

1C-Bitrix

I write my delivery handler based on the code:

CModule::IncludeModule("sale");

AddEventHandler("sale", "onSaleDeliveryHandlersBuildList", array('CFTeaCourier', 'Init'));

class CFTeaCourier
{
  function Init()
  {
    return array(
      /* Основное описание */
      "SID" => "courier",
      "NAME" => "Доставка курьером",
      "DESCRIPTION" => "Доставка в течении дня",
      "DESCRIPTION_INNER" => "Доставка в течении дня",
      "BASE_CURRENCY" => COption::GetOptionString("sale", "default_currency", "RUB"),
      "HANDLER" => __FILE__,

      /* Методы обработчика */
      "DBGETSETTINGS" => array("CFTeaCourier", "GetSettings"),
      "DBSETSETTINGS" => array("CFTeaCourier", "SetSettings"),
      "GETCONFIG" => array("CFTeaCourier", "GetConfig"),
      "COMPABILITY" => array("CFTeaCourier", "Compability"),
      "CALCULATOR" => array("CFTeaCourier", "Calculate"),

      /* Список профилей доставки */
      "PROFILES" => array(
        "courier" => array(
          "TITLE" => "По городу",
          "DESCRIPTION" => "Доставка в течении дня",
          "RESTRICTIONS_WEIGHT" => array(0), // без ограничений
          "RESTRICTIONS_SUM" => array(0), // без ограничений
        ),
      )
    );
  }

  /**
   * настройки обработчика
   */
  function GetConfig()
  {
    $arConfig = array(
      "CONFIG_GROUPS" => array(),
      "CONFIG" => array(),
    );

    return $arConfig;
  }

  /**
   * подготовка настроек для занесения в базу данных
   */
  function SetSettings($arSettings)
  {
    foreach ($arSettings as $key => $value) {
      if (strlen($value) > 0) {
        $arSettings[$key] = doubleval($value);
      } else {
        unset($arSettings[$key]);
      }
    }

    return serialize($arSettings);
  }

  /**
   * подготовка настроек, полученных из базы данных
   */
  function GetSettings($strSettings)
  {
    return unserialize($strSettings);
  }

  /**
   * метод проверки совместимости
   */
  function Compability($arOrder, $arConfig)
  {
    return array('courier');
  }

  /**
   * собственно, рассчет стоимости
   */
  function Calculate($profile, $arConfig, $arOrder, $STEP, $TEMP = false)
  {
    return array(
      "RESULT" => "OK",
      "VALUE" => 100
    );
  }
}

Is it possible to calculate the price in the Calculate function based on the property of the order, which the user selects already at the stage of placing an order?
