How to do advanced formatting of e-newsletter

Can one format the e-newsletter plugin to look something like this: http://campaign.r20.constantcontact.com/render?ca=3daa35da-e0e2-4123-bb2c-05652c11dc3d&preview=true&m=1112375230061&id=preview

I can only see one text box in which to do the formatting. I would like to create content blocks, like the one in the link. Any way to do this?
