Multiple Email Contacts

I would really like to be able to add more than one contact email for my clients. We work in disability care, and every single one of our clients has carers/support workers/NDIS coordinators etc. They all need to receive appointment reminders and automated emails.

As it stands, there is no way to automate this. I cannot express how much of a difference it would make!

Is this in the works? Is it even possible?
