I have a Zoning system, but when I go to edit the Summer schedule for Zone 1, the changes are listed in the Summer schedules for the other zones. Why can't I edit schedules independently in a zoning system?

Within a S40 thermostat, there are four unique programmable schedules:
Summer, Winter, Spring/Fall, and Save Energy. When zoning is installed, there may be up to four zones, but there is still only one main thermostat controlling all schedules. Therefore, all of the zones are looking at the same Summer schedule. Currently, the Lennox S40 does not support individual zone schedules.
