Customer Site - Default Country

Hi

      Any one please help this issue.

1.We have two Setoff Books one is in India and another one is in Bangladesh, My problem is

   When we create the Customer site the default country value is taken as India for this both companies, now we need when we create the Customer site in India the system should take the Country as "India" and when we create the customer site in Bangladesh the system should take the country as "Bangladesh" by default.

Thanks in Advance
