Measuring average stresses across a cross-section

I have come across a building code requirement that limits the "tensile yielding in the gross section". Is there a good way in Solidworks Simulation to check that no cross section average of a structural member (say, a channel) exceeds a certain stress limit?  From what I've researched, you can use a split line to create a face, where you can put a sensor, but you have to do that for every section you want to measure, while I want to be able to check across all cross-sections.  Is my best bet just to run the simulation and then go back and put sensors on any relatively hot spots?
