Since this isn't easy to work around in the FFF settings, I use a template to take the column, sort the entries, compare the string, and then replace if it matches:

program:
	f = list_sort($#fanficcat,0,',');

	if contains(f, '^Crossover, Mass Effect Trilogy, Mass Effect: Andromeda$', '1', '')
	then 'Mass Effect Trilogy, Mass Effect: Andromeda' 

	elif contains(f, '^Crossover, Half-Life, Portal$', '1', '')	
	then 'Half-Life, Portal' 

	else $#fanficcat

	fi

But my current solution working fairly well, so it's not a big deal either way.

Interesting. You are using list_sort() and contains() to test (sort-of) that one list is a subset of another list.

Question: Assume existence of a function list_is_subset(s1, s2, sep) that returns true (a non-empty value) if all the items in s2 are in s1. In this case, would you expect this example of the function list_subset() function to return True?

program:
    fanficcat = 'AAA, Crossover, DDD, Mass Effect Trilogy, Mass Effect: Andromeda';
    list_is_subset(fanficcat, 'Crossover, Mass Effect Trilogy, Mass Effect: Andromeda', ',')

All of the items in the second parameter are in the first parameter, so the second parameter is in fact a subset of the first. The items 'AAA' and 'DDD' in the first list are not in the second list, which is ignored.
