Rota notifications

Hi

I would really appreciate the ability to send out rota details by date rather than service and date.
We have a varying patterns of service over the month and I would like to be able to notify users for the next Sunday regardless of the service involved. Most Sundays we have 2 (different ) services and some weeks 3 services on the same date, but all are different service ids.

Also, some integration between service/rota entries and the calendar would be helpful.

Thanks

Chris
