How do I name a range in google docs?

The Google Apps Script API for Docs has a number of methods defined that work with Named Ranges in Docs. While I am familiar with Named Ranges in Sheets, I cannot find a way to name a range in Docs.

Does anyone know how to name a range using the Docs UI? (obviously one can do so programmatically).

How do you name a data range?

Select the range you want to name, including the row or column labels. Select Formulas > Create from Selection. In the Create Names from Selection dialog box, designate the location that contains the labels by selecting the Top row,Left column, Bottom row, or Right column check box. Select OK.

I was wondering about that also, but it looks as if it is not possible to edit or even see named ranges in the docs UI.

Lets hope, this will be changed in the future...
