Hi Sandy,
An automatic linking method is something we're working on, but we don't have the capability yet.
It's also possible that the speaker was referring to FamilySearch's new tree. They sometimes refer to that internally as "their wiki tree".
By the way, manual links from WikiTree to FamilySearch are easy. See http://www.wikitree.com/wiki/Adding_links#Links_to_Other_Websites
