Kapacitor OpsGenie integration: Have more options

Hello All,
I want to understand Kapacitor API integration with OpsGenie.
I followed the below instructions to send alerts to OpsGeniow and it is working fine
http://docs.influxdata.com/kapacitor/v1.5/nodes/alert_node#opsgenie-v1

When an alert gets generated by kapacitor to OpsGenie.
Opsgenie only recieves the message and time the alerts are generated.

Is there a way to generate an alert which has a unique alertID for the change in state. So that the alerts will have its own unique ID.

Is there a way to add subject() field as in mail alerts for OpsGenie alerts.
