Lists, and subsets take up space within a model, so if you need multiple subsets of the same list, consider whether they would be better as separate lists. This is especially valid if the lists do not overlap and they are being fed from a Data hub. For overlapping subsets or if there is a need to “consolidate” the value back to the master list then subsets are a valid construct for model efficiency
