2D Elements and Dynamo Functionality

I have a question regarding the control of 2d elements on drawings with Dynamo.

To what extent can I control and deconstruct annotation items in a drawing view? An example is that I would like is to grab this annotation and use it to calculate a perpendicular line that splits the geometry of the floor area. This way I could theoretically grab the separate areas courtesy the placement of the tag.

This is an example detail component


You can manually select components of the element, but I would like to, for example, grab the individual reference planes embedded in the family. I can align the element that way to other geometric components but I don’t see a good way to grab that information via dynamo or the Revit API. At least not as far as my knowledge of both those things go. I have also struggled finding good information about this via typical channels.
