Edit when a task was done

Sometimes I have a task that is supposed to be done today, and it is in reality. For some reason, I don't mark it complete in Capacities. I notice it the next day or a few days later. That's when I click it complete and it has the wrong completion date. Not a huge deal. If it is a recurring task that generates based on completion date, it's still not a huge deal, but it is slightly incorrect. I will often correct the upcoming task.

Currently, the Completion Date, Done Date, Closed Date (whatever it is called) is set when the task is marked complete, cancelled, skipped, excused, etc.

On a non-recurring task, the Status says Done and the date/time stamp when it was marked Done. There is no way to alter this date/time stamp.

For recurring tasks, the Completion Log populates with the Date of the update and a timestamp. There is no way to alter this information either.
