Is there a way to auto-increment tag info?

... so that file #1 is "0001 at http://www.thisamericanlife.org" while files #432 is "0432 at http://www.thisamericanlife.org"?

Thanks.

Create an action of the type format tag field for the desired tag field
Enter as format string:
$num(%_counter%,4) at http://www.thisamericanlife.org

Select all the files that should get renumbered. In your example this should be at least all the 432).
Apply the action.
The action always begins at "1".
