Same school but different coverage maps

Usually one school has only one coverage map. However, there are some exceptional cases. For example, Don Callejon Elementary school in Santa Clara Unified district has grade range from K to 8. That means that it serves as both Elementary and Middle schools. Interestingly, it has different coverages as Elementary school and Middle school. For such situation, we provide a "radio button" to allow user select different coverage for such a dual-role school, which is illustrated in the following graph.
