Несколько общих списков одного и того же Bean Redbean

Если у меня есть бин ‘product’ и бин ‘upload’, у меня есть два свойства:

$product->sharedImageList;
$product->sharedManualList;
$product->sharedVideoList; // just here for another property
//relating to another bean elsewhere

Они оба используют bean-компонент «upload». Но я не могу назвать их псевдонимами. Могу ли я не использовать один и тот же компонент для двух общих списков? Я знаю, что список разделяемых бинов должен совпадать с именем бина, но fetchAs работает ниже …

$teacher = $c->fetchAs( 'person' )->teacher;

я пытался

$product->fetchAs('upload')->sharedImageList
//getting desperate now
$product->via('upload')->sharedImageList
$product->alias('upload')->sharedImageList

<?php
include_once 'rb.php';

$images  = [

["id" => 2,'name'=>"test image2"],

$manuals = [

$product = R::findOneOrDispense( 'product', ' id=? ', [1] );

$product->sharedImageList  = []; //empty / create new shared image list
$product->sharedManualList = []; //empty / create new shared manual list
$product->name             = "im a product"; // give product a name for giggles

foreach ($images as $object) {
$upload                     = R::findOneOrDispense( 'upload', " id = ? ", [$object['id']] );
$upload->name               = $object['name'];
$product->sharedImageList[] = $upload;
}

$product->sharedManualList[] = $upload;
