Generate Setters: setVal() instead of set val

I want to follow AirBnB Style: https://airbnb.io/javascript/#accessors--no-getters-setters

How can I generate setVal accessors? I always get the set val methods.

// bad
class Dragon {
  get age() {
    // ...
  }

  set age(value) {
    // ...
  }
}

// good
class Dragon {
  getAge() {
    // ...
  }

  setAge(value) {
    // ...
  }
}
