Well, not really, but we're now simply adding up the add-ons and rebuys in the break, and assign them to random players it's not that much of a problem.
The statistics aren't correct, but they wouldn't be anyway, we'd have to note down, who made a rebuy or an add-on, and that'd too much of a hold-up for the dealers.
Also we kinda found a work-around for the tables-thing, we simply don't care too much anymore. In the first tournaments, we tried to identify the players via the seating chart, but that didn't work out, because the chairs of the empty places at a table were often moved by spectators, so the seat numbers were hard to determine in the tournament. And if you ask a player who just busted out of the tournament for his nickname, he's not very happy. We solved that by giving every player a card with his nickname on it as a receipt for his buy-in and we track them with those cards, problem solved.
So far, we're pretty happy with The Tournament Director now, but I'm sure gonna bug you with some feature requests again soon
