Can you dynamically change properties of node-RED nodes

I'm currently working on an application that uses MQTT to communicate between an android app and a LoRaWAN gateway. It uses node-RED on the gateway's side.

I can manually set up on what topic my MQTT output node publishes to. I was wondering if there was a way to make this property of the node change depending on the message it receives.

For exemple, would it be possible to send a topic attribute alongside my msg and payload and use that value to set the property inside the node.

Thanks for the help!

Yes, just leave the topic field blank in the mqtt-out node config and set the msg.topic property on the message to be the topic you want to publish that message to.
