Insert operation in two different classes with one post request

I want to insert mysql and redis databases in their classes at the same time. I tried to use the repository pattern, but laravel's bind method implements the interface to only one single class

The controller is as follows:

class PostController extends Controller
{
    protected $post;

    public function __construct(PostRepositoryInterface $post)
    {
        $this->post = $post;
    }

    public function store(StorePostRequest $request, PostRepositoryInterface $post)
    {
        return $post->create($request->validated());
    }
}

PostRepositoryInterface

interface PostRepositoryInterface
{
    public function all();

    public function get($id);

    public function create($param);

    public function update($id, $param);

    public function delete($id);
}

The question I want to ask is, how can I perform the insert operation in more than one class using this interface?
