Select area objects of the AREA category

Is there any node in 7.0 that enable users to pick the area objects of the AREA category? This is possible for the Room objects, but can’t find anything related to Areas.

I think I figured out how to select elements by category. Am trying to aggregate the area of different Area Objects based on the Area Name. Below is what I have done so far. Now I need the subtotal of the areas named B, and the subtotal of the areas named A-1. Any input will be greatly appreciated.
