A helpful feature to be added would be the ability to schedule unit shifts by day of the week.
For example: several ambulance companies in my area are staffed more significantly during the week days then they are overnight or on the weekends. Adding shift times by day of the week would allow units to be placed in service during the day monday-friday and be out of service overnight and on saturday/sunday. Currently the only way to do that is to go through each station and place units out of service manually.
