Creating UDTs when Using MQTT in Ignition

Can someone help me understand how UDTs are used when using the MQTT Modules?

I am looking to use the MQTT modules but I am concerned of how I will utilize UDTs with it. I’ve seen webinars where the tags are auto created when using these modules and the data comes in using Sparkplug protocol.

I am looking to use a red lion HMI which can publish data to a MQTT broker using their Sparkplug MQTT connector. So then the tags should auto populate in under the MQTT Engine tag provider.

If for example I have 100 pumps that all have the same set of data tags publishing to the MQTT broker using this same HMI, how can I create UDTs if the tags are auto created with the MQTT Engine Module?
