Path of the UDT Instances in Easy Chart template

Hello guys,

I need your help in the following situation:

  1. I made a template for graphic analysis of an thermal points with easy chart, see below:

  2. I have UDT instances created for the thermal points (on Module folder), based on Data Types, see below:

  3. Now I want to add the path to that template to point exactly on the termal points id. For example if I click on the PT730 to have exactly the path of that thermal point in Tag Browser Tree, like bellow:

What I tried was to go on Tag Browser Tree and to bind the expression path of the Descriptive tags on the UDT Instance of the thermal point, but that seem to not change in the UDT Instances, only on template.

Could you help me please in this situation?

Thank you in advance!
