[chirp_users] Import from stock config - option not available

Evening, I'm trying to find the "Import from stock config" functionality in CHIRP and I don't see it anywhere.  The only 4 choices I have are: Radioreference.comRepeaterBookprzemienniki.netRFinder The CHIRP FAQ page indicates "These are canned frequency plans, some of which are built into chirp." Where do I find this "Import from stock config" functionality? Please advise.
