Single Post Page Layout

Hi Tom,

How do I make my single post page layout look just like my homepage. For example, my homepage is set up as "sidebar-content-sidebar," but my single post page is just showing as "content-sidebar." I see the option to select whatever layout look I want on each individual post, but I'm seeking to have it automatically set "globally" as "sidebar-content-sidebar".....so I would not have to set it every time I create an individual blog post.

Hope this make sense...

Thanks,

Bob
