After a credit card donation has been added as successful to a person, is there a method to update it to indicate that it was refunded or voided.

I tried setting canceled_at and failed_at to a date.  I also tried removing the value for succeeded_at (which leads to some unusual and misleading error messages)

The only method I have seen that "sort of" works, is to delete the donation.  But then there is no record of it at all.  Is deletion the only option I have?
