Is there a way to consolidate the summary report while retaining the older summary report intact?
Yes. To do this, in the first scan provide a path (say Path1) in the “Report Formats” page of the MSIA wizard for saving reports. In the second scan, provide a different path (say Path2) for saving reports and choose to consolidate summary reports. At the end of the second scan, Path1 will have the summary report of Scan1 and Path2 will have the consolidated summary report of Scan1 and Scan2.
