how do you make such clean control flow diagrams? Those are sweet 
I could probably explain my thinking a lot better with them as well 
but I do see what you’re saying now. I do think the answer is in nested loops still, and as for your question here
I would definitely use a second for loop that cycled through an array of the tables 
so it would be (without the beautiful diagrams) something like :
for each data table in the array of data tables :
—for each key in the data table’s map :
------create trick name widget
Then for the input to the ‘keys’ value you have there, you would have the output of the last ‘for each’ node - it would be outputting each data map contained in your array of 100+ data tables.
I may be barking up the wrong tree here as well and do apologize also if I’m causing the confusion gotta rest for now but good luck with getting everything figured out
