Add or remove engineer stamp/seal from title block using Data-Shape

I think it will help me to break this graph up and get sections of it to work and then put it all together. For now I want to focus on selecting the titleblock associated to sheets that the user selected.

I am able to select sheets using Data-shapes just fine (see pic below). What I need is to select the title block on those sheets so I can turn on/off the parameter associated to the title block.

I am using two other forum posts as reference (see below). Problem is I don’t know how to translate it using Data-shapes. I could easily copy what they do but neither of them are using data-shapes.
