This is a feature that I am quite surprised to have not seen requested, or already implemented.
When a reseller account is created (cpanel), they are automatically added to the main server ip, and no restrictions are set on which ip address's they can use for domain creation.
The auto setup function deems useless in this sense, as the account would be created, the welcome email would be set, than i would have to go back into whm to set ip delegation's and shared ip settings, than send out a new welcome email with the correct newly assigned ip address.
