As a PI System Admin, I would like to reference an attribute value as part of my attribute data references for a String Builder data reference. For example, suppose I have a parent asset 'Parent' with an attribute of 'XD5' and a child element 'Child' with an attribute 'ID' with a value of '5'. It is currently not possible to build an attribute with a String Builder data reference at the 'Child' level that both:
1. Builds an attribute reference string by referencing the value of an attribute at the current asset level (e.g. 'ID')
Then retrieves the value of a parent attribute (e.g. 'XD5') using the string built in Step 1.
Allowing nested attribute references for String Builder Data References. would enable this functionality.
