Only to a certain extent, of course...region matches are non-negotiable, and in some cases (such as in regions VII and VIII-AAAA) there is an agreement between two regions to play each other in out-of-region play. Still, even then, there remains a little bit of flexibility to schedule at least a couple of matches per year based on compatibility and development strategy...I had a 14-game schedule handed to me this year, which gives me two matches to schedule myself, plus the option to trade in one tournament for two more regular-season games. Better than previous years when the whole 16-game schedule was done for us and handed to the coaches.
