Thanks for all the help, I learned a number of things.  What I ended up doing is use the “Add Reversing Transaction” command on the payment.  Somewhat to my surprise this did pretty much what I wanted to do.  It added a “reversed by” slot to the payment transaction and decoupled it from the invoice.  This left the invoice unpaid.  I created a new invoice for the late fee and used the customer’s replacement check to pay both the original invoice and this new one.  This seems to make the books reflect reality fairly well.  My main problem was that I had forgotten about the "Add Reversing Transaction” command so didn’t think to try it.
