Templating the Email Addresses In Email Contact Point

We are beginning to use Grafana Alerting. We need the address in an Email Contact Point to be dynamic as we have many different teams that will be using this functionality. It is not feasible to create a new Contact Point for every possible distribution list.

Ideally we would like to be able to pass an annotation to the email address field in a Contact Point. Does anyone have any suggestions on how to accomplish this?
