Laravel backpack crud for update and list with relationship

Question

I've got 2 tables with one to many relationship.

1. portfolios
   id
   category_id
   status
   image

2. portfolios_lang
   id
   portfolio_id
   title
   text
   lang

I used backpack crud for portfolios_lang and I was able to create records. I added my logic to store() in my PortfolioLangCrudController. But when I want to update a record I can't make it so fields from portfolios were assigned depending on portfolios_lang I selected. Here is screenshot http://joxi.ru/L21x31Vt08aVgm

The same goes for list http://joxi.ru/LmGP76vHleDbO2

I couldn't find anything in documentation. Is there a way to do those things?

EDIT

EDIT 2 Thank you, I was able to show categories in list

 $this->crud->addColumn(['name' => 'portfolio_id', 'type' => 'select',
            'label' => 'Category', 'model' => "App\Categories",'attribute' => 'name','entity' => 'portfolio.category',
            'key'=>'categoryName']);

But is there no way I can edit related fields from one form?
