The implementation in this mod is kind of hacky. It would be much better if it just allowed us to pick tiles in the regular upgrade planner, instead of adding a separate thing. The most important impact of this, IMO, is that we can't right-click to downgrade and we can't add specific upgrade plans to our character's blueprint library.

Was trying to figure this out as i was trying to go from brick to hazard concrete. Guess I cant use the mod then and its back to copy paste :/

+1 I thought initially it was doing exactly what OP said, disappointed to see it is a separate thing which means extra shortcut clutter.
