Yes. A vital function of the software in „CREATE A NEW ROUND“. In this mode you will be able to create a round from memory without having to have used the app whilst playing. This way you are completely independent and do not have to leave out a single round.
This function also comes in handy when planning a round. As long as you do not save the round, it will not be accounted for in your statistics. Once you do not need the round anymore you can simply delete it or adjust it to how you actually played on the day.
