Add Meta Fractal PHP

I am using fractal next to Laravel to manipulate my collections . In some Transformers I use available include (as shown below).

What I would like to do is to include a goal with array of those includes .

Example:

meta:{includes: {include1: badah, include2: badah},data{dados...}

Code:

<?php

namespace apiAneel\Transformers;

use apiAneel\Entities\AccountPlan;
use League\Fractal\TransformerAbstract;

/**
 * Class AccountPlanTransformer
 * @package namespace apiAneel\Transformers;
 */
class AccountPlanTransformer extends TransformerAbstract
{
    public $availableIncludes = ['acrCod', 'companyType'];
    /**
     * Transform the \AccountPlan entity
     * @param \AccountPlan $model
     *
     * @return array
     */
    public function transform(AccountPlan $model)
    {
        return [
            'id' => $model->id,
            'cod' => $model->cod,
            'description' => $model->description,
            'dep_cod' => $model->dep_cod,
            'dep_description' => $model->dep_description,
            'expense_cod' => $model->expense_cod,
            'expense_description' => $model->expense_description
        ];
    }

    public function includeAcrCod(AccountPlan $accountPlan)
    {
        $acrCod = $accountPlan->acrCod;

        return $this->item($acrCod, new AcrCodTransformer());
    }

    public function includeCompanyType(AccountPlan $accountPlan)
    {
        $companyType = $accountPlan->companyType;

        return $this->item($companyType, new CompanyTypeTransformer());
    }
}
