After hours function

My office hours closes at different times on different days and sometimes early if i have meetings.
Is there a way to set the “After Hours” option for the VR on the fly. In other words, if my office is set to close at 5 PM but i decide to close at 3PM, where can we go to set the “after hours” ON right away.
Thanks

only option right now is to change your config in the Virtual Receptionist
