It's not in the list of default destinations, but you can always add it yourself. The reason that the other destinations are set up as defaults is two-fold: Large Lists (many bosses), and common DKP locations.
UBRS hasn't been a common DKP-worthy zone in roughly a year and a half, so for situations like that, you'll just have to manually create the destinations by going to Admin > DKP > Destinations
Completely understandable, thanks.
