Thank you for your post.
All reports in Store Manager can be customized, you can change report layout, insert pictures (logos), add and remove fields etc. There are many ways to customize a specific Report. Just go to Edit page by clicking corresponding icon. There you'll see "Designer's" toolbar, “Standard” toolbar, “Text” toolbar, “Frame” toolbar, “Align” toolbar.
Also you can create your own reports. By each report name you can identify its purpose and information it contains. Store Manager allows you to work with a third-party program (Report Tool) for report developing and editing. Download User's Manual to learn more about this tool:
