PW2 How can we landscape periodicals in PW2 5.6.5?

Hi.

I daily download periodicals using calibre. This periodical takes the shape of periodical and not a normal book in kindle, which means i get list view as well as snippet view of the article, before i read in detail.

This periodical format doesnot give me an option to read in horizontal or landscape mode.

I was wondering if there is any extension or way out to read periodicals in landscape mode.
