Am I missing something: No way to specify email body template?

So we need to email specific alerts to our our ticketing system for storage devices and we noticed that the email body can only be what the Alert Message drop down menu is, specified on the Datasources > Datapoint. Why?
Can we not specify a different email body template with this product? We just want to create a new "Alert Message" template that is similar to the usual email body that we've been using in our exiting monitoring solution. I understand we can do a 'customized' alert message but then we'd have to do it on every single data point w/in the data-source.  ugh! 

Am I missing something or is this restricted to this method currently?
