Some easily adjustable ready-made areas for aDM adhocs.

I was thinking on the Discord meme of B3 Arabel Sewers and an idea hit me for Adhocs; why not have a selection of easily adjustable areas for adhocs for places like deeper in the sewers and forests around Arabel/Yulash; same could even potentially be done for the underdark. If memory serves, that's the biggest difficulties in running an adhoc is custom building an area for it, no?
