You could do that…my recommendation is only when it is a final version, otherwise you could start to get overwhelmed having to make copies after each day of building.
There is the function to do a backup in the app using the ‘history’ and create a save point. This allows you to save at the end of the day and if anything is off later you can revert to that time easily…otherwise while building and you experience issues with recent changes you made you can use the history and revert to specific time
