There isn't. The choice is either an operational systems choice or a programming choice. Automated systems could well be set up to weight alarms based on expected norms, but given the range of humanity it'd be an amazingly poor system or programming choice to opt for. I fully expect TSA to have requested exactly that. After all, "that would be so much better.".
