Because the classifier runs individually on 5 columns, the easiest way to combine them AND eliminate duplicates is to use the properties of a Pyrhon set to concatenate them, then catch the result as a list to copy and paste into the QP Generator

list_A = [<numbers from list A>]

...

list_E = [<numbers from list E>]

neutrals = list(set(list_A + list_B + list_C + list_D + list_E))

print(neutrals)

Tested without updating the draws and it works exactly as imagined. There are other ways to do this, but the built in properties of the Python set make it the most efficient.
