Accessing or creating Title Blocks in Data Architect

I have a lot of submodel displays without title blocks, so I decided to write a macro to tell me which submodel displays don't have a title block. I've access the list of shape displays for each submodel, but nothing shows up, so obviously the title block is not a 'shape'.

I can see properties to control the appearance of a title block, but nothing that helps me find them or create them.

Have I missed something?
