Hi Clarknd,
REM can generate a variety of reports in a variety of formats and filters and groupings. If you're looking to do custom reporting, there are a few ways to go about it. One, run a Vulnerabilities Export Report in REM (will output a CSV for you). Two, go to Assets, checkbox the machines you want (you can also apply a filter), then click the Vulnerabilities lower tab, then click Export button (export to CSV, tab, or XML). Also we can provide the DB Schema if necessary to let you write your own SQL Query via support ticket (www.eeye.com/clients) or in a future update in REM you can create your own stored procedure to create a custom report.
Hope that helps.
