Stop column division in Pages 10.1

Dear all,

I would like to know how to return to single column writing after dividing a document into 2 columns or, more broadly to change division to "n" columns after having divided it into "m" columns.

I do not want to use a text frame.

Here is what I tried:

• Position the cursor on the next line (line break in the right-most column) then change number of columns (doesn't work)
• Insert section break after the last line of the right-most column, then change number of columns. This works but I inevitably lose a line.

Is there some other way?

The "layout break" of old Pages '09 seems not to be available anymore.

Thanks
