unfortunately 'Flights' is not an option for TD2, perhaps something Corey would consider adding in future, but likely a massive undertaking on the current software, flights is multiple day1 tourneys on the casino software i use, where you set-up a flighted tournament and then register players for flight1 or flight2 duplicates can be registered on either flight, the prizepool and merging onto day 2 is handled by combining flights when initiated, which would create a new draw, combined prizepool, combined total entries etc
