[Observium] Separate emails for alerts sent to contacts

Hi,

I'm looking at using Observium contacts + alerts to replace some alerting we do for customers using Nagios. Is it possible to send a separate email to the primary device contact and any additional contacts specified for alerts in the contact section rather than populating the to field with all recipients on a single email?

If not would this be difficult to implement? We'd prefer not to expose the internal email address that receives our alerts to our customers if possible.

Thanks, Chris
