VCSA currently (6.7 U3) has no ability to import ISO images into Update manager via command line/PowerCLI.
Code capture from VCSA does not show any output, so this functionality is not yet exposed it seems.
Having a means to manage ESXi images via PowerCLI (import, delete, inspect) will be very helpful for Day1 and Day2 operations when you have multiple vCenters (tens) and have to manage various flavors of ESX Custom Images.
Thanks! Version 1.1 now available and on PowerShell Gallery.

Awesome module Alistair, I will give this one a go, in one of my labs and take it for a spin.
Have you considered publishing this to Powershell Gallery?
It would give the module more visibility.
Please see https://thedotsource.com/ for a post on VUM Xtra which addresses this issue :)
This is possible by manipulating the VC Integrity API. I'm hoping to have some PowerCLI code published to Git hub soon that does this and other update manager tasks.
