[scribus] adding colums to an already created page

[Mike Breiding]

I checked here:
http://wiki.scribus.net/index.php/Working_with_text_frames

It explains how to set up columns for an entire document.

I wish to change a selected page only.
For instance, choose page 2 and create 3 equal columns?

I searched by key word in the wiki and only got a hit for a column script.

Am I missing the obvious - as usual.
Thanks,
-Mike
