Hard to tell exactly what you are asking for. Are these things you know how to achieve through the Skyline UI, which you need access to through the command-line, or are you requesting entirely new features?
When I read the requests, some seem possible to me with the command line and a custom report that outputs the values you are seeking. Are you already using Skyline command-line successfully for other things?
Maybe start by detailing how you get what you want from the Skyline UI and how you imagine getting it through the command-line.
Thanks for your feedback.
