How to add Material and Weight on drafting Titleblock?

Does anybody know how to get the applied material name to automatically link and update on a drawing titleblock using link templates? BOM tables have the ability to determine the applied material on a part and the report the material name, but how to do this in a titleblock template cell? Ideally, I would like a link template which can be automatically routed / linked using the SolveLinkOnPresentedProduct cell naming method.

Similar question for Weight - I know how to get the computed weight or declared weight to appear in a titleblock table cell, but can't see how to just have one "Weight" cell that displays either the declared weight or computed weight, if either exists on the part.  BOM tables appear to be able to report a "V_Weight" attribute, but when I try to use V_Weight in a titleblock link template it doesn't work for me.

Would be great if table template cells could be defined with an EKL expression, like Knowledge Reports can!
