Since the gallery is in need of a great many updates and fixes, and we are still awaiting the return of the newsfeed (I will edit and insert the link to that thread HERE ), I would not expect to have a new feature implemented in time for the pack release on Thursday. Especially since it was not mentioned in this month's laundry list.
That said, if you go to the gallery, sort by "most popular" or "popular now", choose the "lots" category, then search "6 unit" using the "item name" drop down option. This brought up a lot of relevant and nice options for me, and it should for you as well. Good luck and happy simming!
