Section scroll links at top of blog posts possible?

Hi guys, is it possible to create a blog collection that at the beginning of the post I could highlight the sections and use an anchor link to navigate to a section?

I know it can be done as a page, but unsure how to do this setup in a collection. I’ll add a photo of what I’m going for and also a preview link that shows the current blog structure.

Basically, the client wants to have a few blog posts that are super long, but not all. Thanks!
