Machine Prefixes in vRA 8?

Hi all,

I haven't gotten my hands on the vRA 8 beta yet (WIP with our TAM), but can any of you that have confirm the existence of machine prefixes? I'm currently working with a customer (vRA 7.6) that is heavily utilizing/managing prefixes via backend vRO code as part of their builds, and I want to know whether or not this feature has made it in the new release or not.

Thanks in advance!
