virtusertable manager

I need virtusertable manager script. When a virtual domain is created '[login to view URL]' a user account is created 'testdomain'. The virtusertable is setup to deliver all email address '' to that user account. What I want be able to do is view and edit entries in the virtusertable for a given domain '[login to view URL]'. I want to ability to add specific addressed to the table ''me"@"testdomain" and optionally delete the global entry that direct all emails to the 'testdomain' account.
