How can I edit the projects in What is the status of our project portfolio?

In the Project Lifecycles view, click the edit button to open the Projects data workbench.
Edit a project directly in the data workbench or select a project and click the navigate button to open it's content area

Use the features of the data workbench to slice-and-dice your data to focus on data and do the analyses you are interested in:

Click Structure and add or remove columns to the data table. Include relevant attributes and indicators to capture important data. A tooltip explains the purpose of each attribute, indicator, and role that you can add.
Click Visualize to view the data in a different graphic visualization. You can save these visualizations to your content repository and used them in other content area pages.
