Create hierarchy in glossary

Regular Visitor

In a glossary I would like to create a hierarchy (not just related terms, but a real tree structure).

In the manual on glossaries ( step 6 specifies mentions that a glossary item can have a parent if it's in a hierarchy. But this page does not explain at all how to make a glossary item part of a hierarchy; can somebody elaborate on that (or improve the documentation)?

I just saw this mentioned at Ignite and the page STILL doesn't describe how to do this. Do we know when we will see this update?
In my Purview instance, the new hierarchical glossary term definition is already available. Whenever you edit a glossary term, you can select the parent term.
