A twist on autonumbering

I have implemented the autonumber solution in one of my applications, and it works perfectly, but had a question regarding the duplication of a record.

In my application, the user enters a bunch of information about an event. When the user clicks the submit button, the On Add > Validate event will process the autonumber script. But in this application, there are many instances where one event doesn't differ too much from another, so using the duplicate function built into Zoho's list view would be perfect...except that the autonumber script isn't invoked.

Is there a method that the autonumber script (or any script for that matter) will run if a record is duplicated?

Thanks,

Leo
