Custom Advanced Query

Trying to make an advanced taxonomy query like this:

array(
‘post_type’ => ‘coupon_type’,
‘tax_query’ => array(
array(
‘order’ => ‘DESC’,
‘posts_per_page’ => ’10’,
‘taxonomy’ => ‘coupons’,
‘field’ => ‘slug’,
‘terms’ => ‘expired’, // exclude expired.
‘operator’ => ‘NOT IN’)

),)

Though it appears this is not possible via the Recent Listings Layout object. Is there any way to create such a query without hacking the core?
