Having more experience in using Ignition now, it’s worth noting that using UDT parameters within template symbols is not recommended. It’s much more efficient and scalable to bind the path to the UDT instance instead, and then concatenate the relative path to the tag onto that.

- it’s impossible to reuse the template symbol for another, similar UDT
