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

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.
