Im usually pretty good at ComplexMaps and implemented a couple, but I have one that is stumping me on how I can implement it. My problem is I have no real "leading data" to key off of and need something else...
It goes a little bit like this:
D123456 THING1 THING2 THING3 THING4
D789101 THING1 THING2 THING3 THING4
