There is a significant feature missing in Piwik compared to GA4. I’m referring to the ability to send sets of items within an event. In GA, we have the “view_item_list” event where I can send an array of products displayed in a category. The data from this event is crucial for determining the order of product display to users and analyzing category page performance.
If Piwik had such functionality, it would greatly facilitate my work. Additionally, it would be even more beneficial if this capability could be extended to send lists for all events, not just those predefined by the system.
