Possible mailbox template addition/mod?

Can the template for ‘Mailboxes’ (when creating a new Siteworx account) be easily modified? Not so important really, its just that after creating a new account, I like to drop the pre-existing ‘postmaster@xyz.com’ mailbox from ‘No Quota’ to just a few megs and add an ‘abuse’ mailbox as well.

Just a thought to remove a few steps in the future.
