One thing I could see, dependent upon how you have TD set up, is player movement - you would want to turn off the movement suggestions, or just decline them until the final two tables. I have a game on my android phone that does a multi-table shootout, where it starts us out with 3k in chips, 10/20 blinds, and we play down to 3 players. Then, the final table occurs, and it's reset, so to speak - back to 3k, back to 10/20.
