Compaibility with WooCommerce Currency Switcher?

Hi,

I am using woocommerce_pay4pay_cod_amount for adding my custom fee.

I also use WooCommerce Currency Switcher plugin and this fee is only in one currency. There is a suggestion to go through woocs_exchange_value filter: http://currency-switcher.com/documentation/#!/section_8

$value = apply_filters('woocs_exchange_value', $value);

But I am not sure if it is really needed? P4P supports it automatically somehow or I am only doing something wrong inside my woocommerce_pay4pay_cod_amount hook?

Thank you for your help!
