Inheriting Template Parameters from Parent

[MichaelAur]

Hello,

We have some custom metadata fields which allow for easy linking of datapoints to our asset management system. We have a number of templates where all the datapoints of the template have this metadata set via expressions which link to instance parameter field. This works well for us, allowing new instances to be setup and only enter the metadata parameters in one location, and if we add new points to a template then the instances automatically inherit the correct metadata.

However we also want to have some 'add on' templates where we can implement these within an instance. We can setup these add on templates however it currently requires us to set the metadata parameter for these child instances even though it is the same data and fields. So my question is, is there anyway to reference the parameters of the parent?

I hope this made sense. I have also included some simplified print screens to hopefully illustrate what im trying to achieve.    

For reference we are running EcoStructure Geo SCADA Expert 2023 November 2024 Update (Build 86.9098)

I also thought I would add that I found the below posts which on one side sounded like it may be doable and the other front that it is a feature under consideration
