Change redirection after validation failed - laravel

I am validating a user registration form

for EX: (Requests validation class)

class UserCreateAccountRequest extends Request
{

    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        return [
            'email' => 'required|unique:users,email',
            'password' => 'required|min:6|max:32'
        ];
    }

}

If the email is already registered I want to redirect to the password reset page.

How can i achieve this using request validation class without putting the validation in to the controller?
