Customer Experience Essentials - allow supervisors or agents able to "soft open" the queues early (before the schedule listed in webex) to begin taking calls

Are supervisors or agents able to "soft open" the queues early (before the schedule listed in webex) to begin taking calls? If the schedule has them set for an 8am open, could they hop in at 7:30-ish and set themselves to available to take those first few calls?
