Customer Master

1. While creating customer through XD01 on initial screen there are various Account Groups already available, we have created some new, now I want when creating a customer only thoses which are created should be displayed for the convience of the person who is creating master data. Is there any way to display only those Account on XD01 initial screen.

2. How I can view the account group of the customer once the customer is created.

Regards
