Thanks for submitting the idea! We’ve added this into our backlog, and will prioritize with other features. We don’t have an ETA at this point of time. For anyone who wants to see it sooner, please don’t hesitate to vote for it.
This is something that makes Skytap (VMWare) a formidable VM package. If Azure DevTest Labs is able to add this feature then user adoption from VMware would likely increase due to other DevTest benefits.
