i replied at wt nrhp formerly listed subtables as for the nrhp templates at commons i first wanted to do some automated runs before the humans start investing time as you might have noticed commons category national register of historic places with known ids increased a lot in size i would add the template to both the categories and the images currently the template isn't clickable yet like the rijksmonument template at this example but that might change in the future a lot of images have known ids right now i plan to extend the monuments api to make it possible to easily fetch these images for reuse so you enter and you get a lot of images of the empire state building
