It can only be done using a custom column and modifying the script. The column can only be second or further as the Name column always comes first in report. Also, report columns are single-line. As such if a user is a member of multiple groups matching the pattern, they can only be specified in the column as a single line with a separator (e.g. comma).
As another option, items can be added to the report as many time as many groups matching the pattern there are members of and then grouped by the corresponding column. You can see the approach in a built-in report, Members of groups. By default, the report is located in container Reports\All Reports\Groups\Membership.
