Applying multiple filters on a single route definition

I have tried ti find a solution but failed so far - is it possible to apply multiple filters on a single route? 

I have tried the following with no luck

PHP Code:

$routes->get('/', 'Dashboard::index', ['filter' => 'auth|second_filter']);
$routes->get('/', 'Dashboard::index', ['filter' => ['auth', 'second_filter']]); 


It seems that the parameter only accepts strings and not arrays and having to define each set of possible filters as an alias is not very convenient
