What DNS features are you missing? Is this a weird UXG limitation?
I have a UCG-Ultra and was able to set up DNS just the way I wanted. My needs aren't extreme, but I was able to set up a wildcard entry (*.apps.domain -> 192.168.x.y) and fixed addresses and DNS names for various hosts.
The configuration is in a non-obvious place now and has moved around a bit over time. Currently it hides in Settings > Policy Engine > DNS. It shows entries that come from the per-host fixed IP/Local DNS configuration (you can't edit these here) and you can create new entries here (like my wildcard or some other random entry).
