loop back to first post in category

Is it possible, after scrolling to the last post in a category, to show the first post so the user can loop through again and again?

I have two custom entires in my functions.php to assist with most of what I need to achieve:

// scroll posts in same category
add_filter( 'avia_post_nav_settings', 'enfold_customization_same_cat' );
function enfold_customization_same_cat( $s ) {
    $s['same_category'] = true;
  return $s;
}

// reverse order of next and previous
add_filter('avia_post_nav_entries', 'avia_apply_custom_sort_order_to_post_nav', 10, 2);
function avia_apply_custom_sort_order_to_post_nav($entries, $settings)
{
    $temp_prev = $entries['prev'];
    $temp_next = $entries['next'];
    $entries['prev'] = $entries['next'] = "";
    if(!empty($temp_next)) $entries['prev'] = $temp_next;
    if(!empty($temp_prev)) $entries['next'] = $temp_prev;
    return $entries;
}

Thank you
