Pomodoro count history difference when changing settings

[prescripti0n]

I have changed my Pomodoro settings from 25/5 to 50/10. However, this inevitably results in my Pomodoro history appearing as if I have worked half as much when in reality the time spent working is the same. Is there a way to change the old Pomodoros to reflect the new settings. ie. a previous 20 Pomodoro log under 25/5 would appear as 10 Pomodoros.
