I am wondering if anyone has done it or if it is even possible to read the parameter of a parent UDT from a tag change script inside a nested UDT instance?

So in my example I would like to have a tag change script on Tag A and inside that script read the Param 1 value from the Parent 1 UDT.

Been looking on the forum and the manual but haven't been able to find quite what I am looking for yet. Thanks in advance!
