Marketing List Members - add columns?

I am trying to figure out how to add columns such as job title and addresses to the "marketing list" page and/or excel spreadsheet ... we are trying to go through our initial list of 1300 folks to create a 1000 folks list of VIPs.  Having titles and mailing addresses will help.  Has anyone been able to add these columns to the excel spreadsheet that is generated under marketing list members?

Thanks!
