Issues with Filtering Events by User in B2B Group Analysis

🤕 In the context of B2B product, I'm trying to analyze how many tenants (group key) have activated a certain feature. But I want to exclude all events that have been triggered by some users. When creating a report and analyze an event at a group level you cannot filter by user. I tried to create custom event properties that take the user properties I need for filtering. Then I create the report with event analysis at the tenant level (not user), but group). Finally, I filter the event using the custom properties. The result is that the report is NOT applying the filtering. Also, whenever I switch between user and tenant analysis the custom properties get removed from the filter.
