The Txn already happened and its content is immutable - sort of. That
is, transactions (txns) are the atomic unit of data in RT. Those are
the things that make sure the paper trail exists for all the other
objects (users, tickets, queues, etc.)

That said, there is enough rope to do what you want. I don't know
exactly the procedure because I haven't implemented your use-case.

You'll want to expose the Transaction's parent's _Set method. In a
local module that gets loaded have some code like:

# {{{
# paper-trail auditor backdoor :)
# Needed to change the txn's content
package RT::Transaction;

use strict;
no warnings qw(redefine);

sub _Set {
    my $self = shift;
    $self->SUPER::_Set(@_);
}
# }}}

There may be more steps beyond this, but I think you'll need this at a minimum.
