I would absolutely love if this was implemented. The problem, of course, is that new items are sometimes added to the collections. But maybe there could be a way to expand the collection displays when this happens? For example, issuing a new version of the collection display? I still am upset that the elements display rack doesn't have a slot for the element added in Get to Work, and that was the very first pack! Occasionally updating the displays would be very helpful and would allow the collections to grow with time. Since collections usually only grow in a pack anyway, it would make sense to include the new displays in the new packs that added to the collections.
