Automatically Creating a Subdomain for User Accounts

[Eric Pretorious]

I'd like for Plesk Panel to automatically create a subdomain [of the panel's domain] for each username when provisioning accounts.

e.g., If the panel's domain is example.com, I'd like for Plesk Panel to automatically create the subdomain username1.example.com when provisioning the user account Username1.

How can I accomplish this?
