Different sections with different amounts of columns in iWorks Pages

So basically I want to make a document where different pages have a different amount of columns. For example, I want a page to have 2 (equal width) columns while the next page has one (fullwidth) column. I tried achieving this by making a new section, but as soon as I remove a column, the previous section gets reverted back to one column also..

Is there any way to prevent Pages from doing this?

I'm using Pages version 5.5.2...
