Statistica Audit Log Filter by user group

When conducting our local audit trail in Statistica Enterprise Manager, he specific items we are looking for are data deletions, modifications, etc. The Audit Log is not useable for us since there are so many records and no way to filter on user groups containing specifix site for ex. NLGE Geleen. There are too many users for us to filter by individual user. I am wondering if there is a way to get the data that is displayed via the Audit Log but in the same manner as the Audit Trail reports(?) listed under SEWSS Administration so that I can filter by group. For example, the Audit Trail – Subaction report has a pop-up to ask for input data. That would be very handy to have the same but for Audit Log and for User Group.

We conduct audit trail reviews every 6 months, could you please help in building something sustainable for future reviewers?
