APP „Driving Logbook“ – modification of driven distance

Hello,
I would like to ask if there is any possibility to modify driven distance in Driving Logbook application.

Example:
Starting vehicle mileage in application is 7000km and end mileage is 8000km.
But in fact the starting mileage according to odometer is 7000km and end mileage is 8200km.
Is it somehow possible to “update” this difference?
We are using relative odometer for measurement of mileage.
Thank you for any advice.
Michal
