I'd like to have a "Replace with" mechanic for Planet Zoo (or at least PZ2). That way, you would be able to change something in your builds really quick by selecting a bunch of pieces and changing them into different ones with just one or two clicks. All of the pieces would keep their original rotation, making this mechanic extremely useful if you want to change certain beams for example.

Had a scenario yesterday where I would have loved to replace some roof tiles with another, but shyed away from it because it was too much work. Such a tool would be very helpful.

God, this would be so helpful with building custom rock walls. You could just use this tool to make sets for every biome
