This shouldn't be necessary. You can use unlang to update the User-Name,
e.g.

    if (User-Name =~ /^(.)(.*)$/) {
      update request {
        My-Flag = $1
        User-Name = $2
      }
    }

(assuming you've defined My-Flag in the dictionary, or you could use
Tmp-String-0 or similar).

The above assumes you've stuffed one extra byte in front of the User-Name.
If that's not what you've done, then it will need updating appropriately.

Brian.
