WoodGuy a Dagwood was based on the main Male character of a long ago funny strip called Blondie. He often made a stacked meat sammich of the finest order, and they were called a Dagwood. Modern day "Subs" are a type of Dagwood. Of course Hoagies and Grinders are an iteration of the sub. All good eating, and the rest are Semantics. As I pointed out, a "subway" doesn't work into this category, and is just a trashy sammich with poor ingredients, and no craft whatsoever.
