Forward Networks NQE is very powerful.  The information is there.  The examples are clearly written for copying and pasting to create or combine new queries.  

This NQE lists the AWS Hosts / Instances with MAC address(es).  Listing the instance type (ex: t2.micro) enables sorting by size.  Or, finding whether the instance is up or down.  Or simply listing all instances across all accounts.
