I have a UDT instance that has a folder in its definition. I want to be able to add other types of UDT instances to this folder in run time is it possible?

I have been trying system.tag.configure, but I keep getting

> The target path does not have item 'myNewTagName' for overrides, and cannot accept children tags.

Another way I could ask this question is how do I represent a list of tags in a tag? I was thinking I could make a folder in a UDT and then add and remove tags as necessary during runtime.

@Jonathan Did you ever figure anything out for this, I'm running into a similar issue. I'm able to create a udt instance, but when I try to write to a tag within the udt instance it instead creates a custom property and writes to that instead.

To write to a member tag of a UDT instance, you can simply use `system.tag.writeBlocking()`. If you must do overrides on members within `system.tag.configure`, you will need a nested `tags` list of dictionaries with the properly formatted details. (Non-trivial, unless you work from `system.tag.getConfiguration`.)

@pturmel I ended up working around it by using your suggestion to simply write to it after the tag is created.
