Sorry I didn't see this thread and I responded in the other one linked in this message. I don't have an environment I can test in but I think an extensibility set on the machine provisioning pre event you can likely override this. I am just boggled by the decisions VMware makes sometimes it's like they are in a bubble. For those of us trying to use vRA on top of some long established ways of managing our virtual environments changes like this can break all sorts of things. Regardless of whether its a best practices sort of thing and something we should embrace this will not be well received by many.
