Using Alias in Notification Rule Name and Message

Hi All,

I have configured a dashboard and I am trying to configure alert and I am facing an issue where I cannot reference an alias from my dashboard in Alert Rule Name for Message body.

I was using Cloudwatch datasource and had a metric to view unhealthy host count from load balancer. I navigated to Alert. Created an alert and tried referencing rule name "Unhealthy host count alert for {{LoadBalancer}}
But this doesn’t work and a literal {{ LoadBalancer }} is added to alert name. This is also the case with the alert message body.
Also, when I configured the alert and try to send it to victorops. I don’t see the image_url field being populated in victorops. I made sure the include image option is selected in alert configuration.

Please help.
