Here is another one missing this feature! I'm using a Netscout AirCheck G2 that claims it has support for Aruba AP-names, but wondered why I wasn't seeing them in my Instant networks and stumbled upon this post.
Also testing The Bald One's excellent "WiFi Ping" tool [*] and was going to suggest as an improvment to auto-detect AP-Names from the Aruba Vendor Tag, but again, it's not going to help me as I mainly work with Instant networks.
So, I'm really hoping to see this feature in future releases, as it would be really useful when throubleshooting roaming issues.
