Option to customize the "Appointments Reminder" emails so that ithey can be sent further in advance:

For example, the ability to send on Thursday for the following week's appointments Monday-Sunday

All of these options are tied to the day the job is run, so there is no way to specify how far in-advance the job should be looking to send updates.
