This is really a question for Scott Hall. But anyone else that wants to chime in - go ahead.
1. What areas do you want to report and what calculations do you want to display?
2. Would you be willing to place a text box with a leader line to each area perimeter? Each would just need to call a specific macro related to that object - such as property boundary, building perimeter, garage perimeter, etc.
3. A separate text box would call one or more macros to display the desired report.
