Yes, in our Qlik Sense App for review, it combines the likes and comments from all the related posts so we can see a sum of all engagement, though in Community the posts & likes don't appear as "merged". We try to close duplicate posts so that users and product managers can see all updates & comments in one place, rather than chasing down or copying comments/status updates!
I know that pivot table and other tables are getting over-hall so I will check in on these requests.
