Hi Mat The filter evaluation system maintains two lists/arrays: one is the current run, and one is the accumulated results so far. The arrays aren’t stored in variables or named, so it isn’t possible to select/refer to any other arrays.
Your intuition is correct that filters would be a lot more powerful if they could work with more complex structures, particularly dictionaries of key:value pairs.
