BY THE POWER OF GRAYSKULL... YOU DID IT!!!
I am now able to see the total count of occurrences per rule, for each device.
All that is left for me to do now, is research a little bit more to manage the format of the query results, and figure out a way to sort that count column.
Outstanding work!
Thank you very much for all of your assistance.
I will go ahead and mark this thread as "Answered", thanks to you.
