Parser for Multi-dimensional Array with the same key

Consider the followings:

PHP Code:

$template = 'Hello {name}, your partner is {partner}{name}{/partner}.';
$data = [
    'name' => 'John',
    'partner' => [
        ['name' => 'Mary'],
    ]
];

$parser = \Config\Services::parser();
echo $parser->setData($data)->renderString($template); 


It renders the following output:

Hello John, your partner is John.

Just wondering how do you access partner's name while it has the same key name. I have tried dot notation , but it seems it doesn't support that.
