How i can add 2 or more descriptions on a card?

[krafik]

I have a code:
`$client = new Client();
$client->authenticate($apiKey, $token, Client::AUTH_URL_CLIENT_ID);

$manager = new Manager($client);
$card = $manager->getCard();

$card
->setName($_POST['nameProj'])
->setListId('5ac91a71bd573908d72377cd')
->setDescription('NewDescr')
->setDescription('Newdesct2')
->save();`
When I add second "->setDescription('Newdesct2')", the first one is not working. How I can fix this?
