DDS_Topics.yaml Multi Instance

Hello

I have a Pixhawk 6x running PX 1.14.3 mounted on a Holybro Jeston board. Just been trying to map the battery status uORB message to ROS2 using the dds_topics.yaml file. After uploading the rebuilt firmware (still 1.14.3) I can confirm that the battery status topic becomes available however, the information is incorrect. From further inspection there are 2 instances of the battery status uORB message being published in the Pixhawk. The one that correlates to my battery input is the second instance. Is there a way in the yaml file to specify the topic instance to publish to ROS?
