Change the Fee for Payments.CashOnDelivery plugin ?

Im interest about the Payment method Restrictions Plugin and trying to find to change the Fee on Payments.CashOnDelivery.
My restrictions is:
For Country=Cyprus, COD Fee=3€
For Country=Greece, COD Fee=1€

In your site you are clearly sed “Plugin helps to restrict existing payment methods and to change its fees by customer's address, customer role, date of order, order amount and shipment methods, checkout attributes and product specifications, etc.”

How I can change the Fee for Payments.CashOnDelivery plugin ?

Thanks in advance
