Question is more less in the title. 

So far, the script opens a content diagram and displays an embedded tables within a content diagram. I need to loop through each embedded table in the content diagram and manually “refresh” to ensure it is displaying all contents on the table. Currently, if you don't do the manual (UI-based) refresh, you only get a single instance showing in the instance table.

I think another option could be to go through the tables  “Usage in Diagrams” tab in its specification and open the content diagram that way. For some reason it loads correctly when you go that route. I am just not sure how to access the “Usage in Diagrams” section of the specification in a script. 

Any help would be appreciated.
