Change Blog Layout Style

Site URL: https://www.kinetix.com/status/

Hi there,

I'm looking for help adjusting the blog posts per row on our company's status page, used for outages. I don't want to change this using Site Styles because we have another blog that I would like to keep at 3 posts per row, as a grid.

For the status page, I would like the content to appear stacked and the title to appear centered.

Below are screenshots of the settings I'm looking to achieve (stacked), and how it's currently set (grid):

Please help, thanks!
