I do already use clocking for certain areas of activity.  However, I
would need "nested" clocking, i.e. a clock for "at work/not at work"
which I can clock into at the beginning of the day an out of at the end
of the day and within that the ability to clock into to and out of
various activities.  Is that possible?
