Using “Attribute Templates” I’ve set up a string attribute with “Allow Multiple Values” checked.
I can link the children of that attribute into the expression system Example: If the Name of the attribute is “REV” The linked children (Multiple values) show up as in the expression system as... REV REV REV And so on…
The question is... I want to write to the “REV” attribute using “ug_setPartAttrValue” Using this syntax in the expression system ug_setPartAttrValue("REV",A1)
It will populate REV which is the first attribute in the list. So it is respecting the basic name attribute name "REV" but it only places the value in the first value slot of 
What expression syntax will allow me to write to the specific children of that attribute???
