Dependency field mapping unavailable

Dependency field mapping unavailable

Hello,

I am trying to use the map field dependency feature but it does not show up in the setup options for any of my modules.  I have tried adding brand new pick lists as a test to make sure they were not previously mapped, and they are not system-required fields.  Is this feature only available in CRM Plus?
I have tried this in multiple modules (Accounts, Deals, Products, etc.)
