I haven't seen anything like that in the U.S., so I don't know what we would call it. We use a machine of the same size called a "Bobcat", which looks like a tiny front-end loader. I think the "skip-loader" is strictly British. The model looks good to me. If the phi file is causing the subsidiary geometry to be embedded in the cr2 file, it should be easy enough to strip it out and replace it with referring lines. Although I admit it would be better if it creates the referring lines instead of embedding the geometry. It may be too late to amend P5 to allow that, but it might be in a later update.
