The problem I am running in to is that I cannot setup working shifts for the techs.  I do not want a ticket automatically assigned to a technician that is not working at the time. I have 5 people who work during the day, 1 person who works night shift and 2 people who work weekends.

Is there a way to set up a schedule of people that the round robin feature looks at prior to assigning a ticket? I need it to verify tech availability prior to assigning the ticket to them. 

How can i enable this or set it up?
