Fixlet Remediation by Computer Group Report

We have been using the Fixlet Remediation by Computer Group Report that is listed in some of the forums. We use a Custom Field named Change Request that we store change numbers in. We would like to add that field to this report. I was able to put the Change Request in the column header, but need to know how to pull the actual Change Request numbers from the database and put in the report. How do i go about doing this?
Thank you
