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.

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