What you're doing sounds about right.

What does your SkinScript look like?

In the ScinScript, you need to determine what data to use based on 
self.id. Here's the SkinScript I use for a similar function; I'm 
creating "virtual" instances of one ZClass, based on instances of a 
different ZClass from another Specialist. In this case, the other 
specialist is "Responses".

WITH Responses.get_data_for_code(code=self.id) COMPUTE
   subject_name,
   rater_name,
   relationship_name,
   response_code,
   process_step
