Sync Paddle Logger between two devices

I take an old iPhone on the water, and want the data to sync to my new iPhone that's kept safely on dry land. The basic workout data (such as time, distance, route) are pulled across by Apple Health to Paddle Logger on the new iPhone because I'm logged into Apple Health with the same Apple ID on both devices. But, extra details such as trip title, craft type, photos aren't pulled across.
