Mailchimp Campaigns Archive

Hi all,

As you will know there is a way to add a campaign archive to your website to show all previous sent campaigns.

What I would like to do now is to modify how these archived campaigns look on the website. Currently they only show up as plain text that, when clicked, takes you to the Mailchimp campaign. I cannot for the life of me find out how to change how this looks.

Is it possible? Has anyone done this before?

Many thanks as always.
