DHCP Reservations & DNS Host names

I recently converted from UTM 9 to XG, and overall I really like the new interface.  One thing I'm struggling with is DHCP reservations and custom DNS entries to match.  In UTM 9 these were very nicely tied together on the same screen when you defined the host item.  The only way I've found to do this so far is create separate unlinked entries in the DHCP and DNS sections, which is more cumbersome and far less clean.

What am I missing?  There has to be an easier way to do this like we had in UTM 9, right?
