I suppose technically you could sign up for future tournaments, so perhaps I'll dial back making them a month in advance if this happens and it starts getting exploited. One of the big points to address is having people more present and conscious about signing up for tournaments, so you could sign up for the next day, show up and play, sign up for the next day and so on. If there's a day you really want to play more than 2, burn a little DEC or skip a tournament the day before.
