How do I can all sides of something, including bottom?

Still playing around with my Inspire. Not that I have any real work to do it’s basically all playing around.

Anyways, some stuff I have (some that’ll fit on the turntable, some that won’t) don’t just have flat bottoms, so I need to be able to scan their undersides. I’m pretty sure if I tried rotating it by hand when scanning (or paused during a scan) that probably wouldn’t end well. So how do I scan the underbellies of stuff and combine it with the main scan?

You take multiple scans and you combine them in merge

Is there a written tutorial, or at least a narrated video available to demonstrate the process? I am by all means physically possible not a visual learner and I could barely pick up anything from watching that video.
