We have had success with guides, but we also have use cases where we need to present completely virtual guides, almost exactly like the Demo of Guides.

At the moment Guides does not seem to support a hologram maintaining the exact same position / orientation across multiple steps. We currently need to hand place holograms that need to be in the same location across multiple steps and this leads to small inaccuracies over time.

It would be very useful to have an option to anchor a given hologram that was placed in a particular step and mark that it should maintain visibility and position / orientation through all future steps until it is marked as no longer needed in another step.
