Even if you send a message to the session, if you cant directly correlate the instantiated markup to a UDT instance, then how can you know which markup should receive the message?

And if you CAN correlate the instantiated markup, could you not create a custom property on the map that reads your UDT instances and then a script transform that updates any instantiated markups that match?

I feel like that would be easier than sending messages
