So, if I understand correctly, you will be suppressing specific sections of the report, not changing the groups around. Is that correct?
If you set up a parameter (I'll call it {?ShowSections}) that will take the values 1, 2, and 3, here's what you'll do in the report:
NOTE: You'll be working in the suppression formulas. DO NOT check the "Suppress" check box for any of these sections.
- Go to the Section Expert.
- For the Part group footer, use this formula: {?ShowSections} = 3
- For the section where the overall summary is located, use this formula: {?ShowSections} = 1
This should get you what you're looking for.
