I'm working on a project that aims to change the format of all national competitions, among other things. However, I've encountered a problem. Qualifying for the World Cup, for example, for Africa involves 56 or 57 nations (depending on the host country of the World Cup). Unfortunately, I haven't found a way to create two different sets of rules for these two cases. Background for two sets of rules is that with 56 nations, the bottom 16 nations go into a preliminary qualification round, and with 57 nations, the bottom 18 nations do so.
Does anyone have a suggestion on how I can implement this?
