Off grid blog overview homepage

I love Cali, but the home page is a bit boring with all the blogs listed in those 2 columns.
Is it possible to place a larger thumb or maybe even a banner in between?
Now:

Blog - Blog
Blog - Blog
Blog - Blog

want:
Blog - Blog
Big Blog
Blog - Blog

Hi,

Thank you for contacting us.

I am sorry, currently there is no setting for that. You’ll need to make your own code changes to make it possible. I’d recommend hiring a WordPress coder in case you’re unsure of doing so by yourself.
