custom email delivery INTEGRATION and graph tokens in auto alerts

Looking for a way to change the BODY of an automatic alert that would be sent out to our clients based on the STATUS of the Notification is it in ACTIVE? OR ACK? OR CLEARED. We come from another monitoring tool (check_mk) that supported flexible notifications via scripts we could create and integrate into the core alerting system. It seems that we are limited to one template which makes our alerts to clients a bit confusing. 

Also in automatic alerts it would be nice to have a TOKEN that would allow you to embed a graph of the datasource over the last hour showing visually when the issue occured. It seems that all that is supported is RICH text

 

Sincerely,

Miguel
