yeah, so all i wrote is still valid
1. Run your flow
2. Flow does this "flow that does some web part editing in SharePoint. There are specific routine tasks that need to be performed (such as putting the web page in edit mode, putting the web part itself in edit mode, choosing some of the dropdowns that are constant and filling in, and publishing the page.)"
3. As soon as tasks from point 2 are complete, flow displays message boxes (or better custom form) with information: "Perform manual tasks and hit continue" or something along the line, you can even add dropdown with next task flow needs to do once you hit continue
4. When you hit continue, flow goes to next page in a loop
