For simplicity can any crossover that an Arrowverse show participated in be counted towards the show's canon rather than trying to figure out which characters specifically appeared in each specific episode of the crossover? So for example Supergirl would count Invasion, Crisis on Earth X, Elseworlds, and Crisis on Infinite Earths, but not the earlier Arrow and Flash only crossovers.
