To my knowledge, there is no direct way to update in the middle of a game using TD. There may be a way with the auto-export to a website, and then pulling the information from the website to show on the screen (I have zero experience doing something like that). In order for TD to include it with the stats, the tournament has to be completed - one winner. However, as the tournament is going, you can pull up the in game stats and see how they are doing, but just for that game.
I don't recall if asking for something like you are has been asked in the past, certainly not recently. On the status update option that may or may not work, I do know that you would need to have internet to push the information to the site as well as pulling from the site.
Hope this helps you out some!
