One scroll for vertical Collection List

Hey all,

first and foremost, this is an awesome community.
Found all answers to qzillion questions so far, but this I haven’t yet.

I’m making a blog, and want to display one blog at the time.
This I have achieved by 100 VH for Collection Item, and it works perfect.

Here’s a preview:

But I’m stuck on scrolling. I would like for user to scroll effortless between Collection Items, not to keep scrolling and scrolling.
So the effect would be upon a scroll (on desktop or mobile) it automatically shifts and centers next Collection Item.
No animation, no fading, no slide in/out stuff, just simple when you scroll it centers you on next Collection Item.
