Allow single agent to turn his availability on/off, without affecting the Brand availability

Many teams have agents that are not always 100% dedicated to customer service or are away from their desk. It would be very useful to have a switch to turn availability on/off on the fly (like the Brand switch). This would override the routine working schedule set in the profile for the same day, with the option to turn availability on again in 1 hour, 3 hours or in the next working day 8as set in the schedule).
