Sci-Fi Objects, walls, and floors

I bought this very cool map maker tool off of steam in the hopes of having a quick and easy way to create Science fiction style maps for my game. However, all I found was very many workshop objects created. I saw in a reddit post made long ago (Few years back) That you guys were planning on creating a sci-fi side for the map maker use. I haven't seen anywhere in your goals on that, nor have I seen any suggestions for it. I wish I could use the workshop items, but it doesn't feel the same when even the walls and floors are objects and can't have stuff placed on them. Please add Science fiction elements to your to-do list and I would be happy to continue using this amazing map making tool for my sci-fi games.
