I've seen an example of a dynamic configuration [here](https://discourse.nodered.org/t/dynamically-set-mqtt-broker-configurations/89902) but I wonder if the MQTT Client ID can also be set dynamically.  
I want each device to set their ID to the device's serial number, so doing that manually across all devices is not a good solution.  
Is that possible?
