vRA 7 - Related Fields

Are related fields, or dynamic menus, available in vRA 7? I have customers that use this pretty heavily, and if vRA 7 breaks it, we'll need to re-architect our design.

Here's what I'm talking about: http://www.virtualjad.com/2013/05/vcac-property-dictionary-customize.html

The mechanism doesn't seem to be the same in vRA 7, and I can't figure out how to modify the process for 7.
