[Theme: Hatch] Number of Posts on Homepage

Hi,

I’m using the Hatch template.
In the categories, I want to show 8 posts.
On the home page, I want to show only 4 posts.
I asked the theme to show 8 posts at the ‘reading settings’.
Is there a way to make an exception for the home page? (maybe somewhere in the editor…) Or the other way around: can I put the ‘reading settings’ on showing 4 posts and make an exception to show 8 posts at the categories?

I hope that one of you knows how to solve this problem!
