Perhaps a tool you can use is one of the best kept secrets around. NASA has a free Schedule Test and Assessment Tool for which you can apply for access based upon your use. It is an incredible tool, and has a schedule comparison feature in it along with some other features that will shock you that are free as some companies are charging thousands of dollars for the same features. The NASA software catalog website for STAT version 5.0 is https://software.nasa.gov/featuredsoftware/stat
Be honest in your use of the software on the application. It only takes a couple of days to gain access if approved. Good luck.
