Off the top of my head, you can do a Project Report and Group by Portfolio --> Name and then by Project --> Program Name. You can also filter for the projects that you want to see (e.g., status, timeframe). Once the report renders, it will give you a Summary Tab, where you will see…
Portfolio ABC 10
Program XYZ 3
Program 123 7
Portfolio DEF 21
Program HIJ 10
Program 456 2
Program 789 9
