Would like to request a feature for an "On Call" status.

We use this so that technicians know when they are going to be on call for a period of time, in addition to their normal schedule.  However this status assumes the tech is not available when assigning requests.

Example:

Most of our technicians work from 8 am till 4 pm.  For 2 weeks out of every 12, a pair of technicians is also on call from 4 pm till 11 pm.  Would like this "On Call" status to treat the tech as if they are available.
