Start with importing the "interesting moment" program from Marketo program library. I think many of these are covered.
This document will show you how to set up interesting moments in your flow step: Using Interesting Moments - Marketo Docs - Product Docs
Most of these scenarios are pre-made in the scoring program you downloaded during Foundation training. Here's a screenshot of one smart list you'd need to edit from "in past 1 day" to "in past 7 days", but if you're using this standard scoring that Marketo makes, I'm sure you can just add an interesting moment to your flow steps instead of having two smart campaigns running - one for scoring and one for interesting moments.
