One trick is to set up a vertical cable tray, then use the section tool to rotate it into place, like you tried, but without needing extra software.
If you’re installing these for real, though, setting up under-desk or wall-mounted trays can be straightforward with the right tools. I’ve picked up a few from https://tecnotools.com.au/collections/under-desk-cable-tray that are easy to fit against walls or even under desks, and they keep everything pretty tidy.
