Integration to Kafka

Hi guys, i am trying to chirpstack-as integrate to kafka, but i have one question.

am configured this section in chirpstack-application-server.toml

[application_server.integration.kafka]

    brokers= ["172.16.10.10:9092"]
    tls=false
 
   topic="ChirpstackAsTopic"
   event_key_template="application.{{ .ApplicationID }}.device.{{ .DevEUI }}.event.{{ .EventType }}"    
  
     mechanism="plain"
     algorithm="SHA-512"

this config is working, but i need to send data to two different topics in Broker.

topic="ChirpstackAsTopicA"
topic="ChirpstackAsTopicB"

someone have any suggesstion ?
