Hello, I am using the MQTT engine to subscribe to the Mosquitto broker in order to receive my JSON payload. I am receiving all the messages that are creating new tags, so I have more than 200 tags, and I want to create UDTs to be more organized later when creating new alarms. Is there any way I can create UDTs from MQTT engine tags?

Are you trying to create UDT definitions from these MQTT tags? You could try creating [reference tags](https://docs.inductiveautomation.com/display/DOC81/Types+of+Tags#TypesofTags-ReferenceTags:~:text=Reference%20Tags-,A%20Reference,-Tag%20simply%20refers) and then using those in the definition?
