Suggestion: Being able to rotate pieces of offroad, holes, etc

A section of the track I'm making right now has a formation of patches of offroad that are symmetrical to each other, but the grass doesn't have a simple square shape, so I can't just copy the terrain to the other patches; I have to do it all over again. This made me think how much time-saving could be to have the option to rotate sections of terrain. Not only offroad, but also walls and others. I imagine this being useful for certain portions of many tracks.

I'm talking about Complete mode. It's the only version I've been using.
