Hello @motk88,
Thank you for reaching out,
There’s no direct option for this, but there are several ways to achieve what you want.
One way is to use a sample code from here https://docs.oceanwp.org/article/375-altering-header-style-by-page
Instead of setting it for a page, you’ll need to configure it for posts or post archives.
Another approach could be customizing the blog code itself.
You could also explore plugins that allow you to assign different headers and footers to CPTs or posts (search here: wp.org/plugins/).
The last option, as you know, is to individually modify each blog post; here is the related article about it: https://docs.oceanwp.org/article/830-header-oceanwp-settings.
I hope it helps.
Best Regards
