I'm trying to create a view of all unassigned tickets. I know that we can filter Open down to just unassigned but we like to have one view for all open tickets and then another for unassigned tickets. I've created the button for it in scp/tickets.php as such: https://imgur.com/SYdvux3But I cannot figure out how to filter down to just the unassigned tickets. Is this possible? I'm using 1.10.1. Here's what I added to scp/tickets.php:$nav->addSubMenu(array('desc' => __('Unassigned').' ('.number_format($stats).')', 'title'=>__('Unassigned Tickets'), 'href'=>'tickets.php?status=open', 'iconclass'=>'Ticket'), ($_REQUEST=='unassigned'));
