Assign more than 10 spaces to the zone controller

Our house has 14 rooms, 20 smart radiator thermostats and one smart thermostat. We want to be able to set the temperature individually in all 14 rooms. Can Tado adjust the zone controller so that we can, say, control 15 rooms instead of just 10? I suspect it's an setting somewhere, which should be adaptable, right?
