Accessing masterdata attributes for text on drawing

[m.epp]

I would like to create a text reference for a drawing frame that accesses the drawing's masterdata and returns "Not Applicable" if the attribute is empty, but returns the contents of the attribute if it has been populated. The lisp logic for returning the "Not Applicable" is simple enough, but I have not been able to find an Ikit command that can pull an attribute from the drawing's masterdata. Does anyone know of one?
