I have a doubt regarding the new territory management feature: It is possible to assign to an account to a territory automatically based on the user's territory (the user that creates the account)?

I have created 2 territories, lets say Australia and Brazil.

Now, Australia contains 2 sales persons, and Brazil two more sales people.

 My objective is to isolate the accounts from these two territories and that if a sales person from Australia creates an account, this account will be automatically assigned as an Australian Account only visible to Australian sales persons.

Is this possible? 

Best regards,

Jaime
