Start timing a round from first stroke entered

Please start the statistics of a round not when one presses START on the mobile phone but when the first club/stroke is made. 

The problem is that a round which is started when one is on wifi, so that the course can be fully downloaded without using data, means that the round time will be incorrect as well as the distances walked etc.

METHOD : Initiate the round on the mobile phone and download the course reviewing the holes in the clubhouse before playing, go to the tee when ready, START the round by entering the club for the first shot.

Thanks
