Add fields to validator in UpdateContactInformation

Do you know how i can override the validator() and handle() method for updating the contact information form in the settings tab?

namespace Laravel\Spark\Interactions\Settings\Profile;

class UpdateContactInformation implements Contract
{
    /**
     * {@inheritdoc}
     */
    public function validator($user, array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|unique:users,email,'.$user->id,
        ]);
    }

Is there perhaps something like the Spark::createUsersWith() method like in SparkServiceProvider? If not, what would be the best way to handle this?
