How to add a third column to my blog on Blogger beta?

[aryayush]

Hello!
I have recently started a blog on Blogger beta. The name is rather long:
Press any key to... No! Not THAT one!
As you can see, the right side of the blog is totally empty. I wish to add a column there so that I can add RSS feeds, polls, quizzes, etc. Is there any way to do so? Basically, my blog has two columns by default and I want three. I have checked out all the available templates and none of them has three columns. To see a screenshot of my problem, click on the thumbnail below:

Thank you!
