Multiple Authors for One Blog Post

Hi everyone,

I have a blog post to publish that myself and another contributer have worked on together, however I can't find a way to display both authors names in the 'written by' section of the article. The drop down list only allows me to select one or the other, not both. Is there any way to put both authors names in the written by section of an article? 

Cheers!

Two ideas - creating a shared account with both of your names on it or writing your fellow author's name at the very beginning of your post in huge letters.
