Unfortunately there is no way way to have collections on the home page.
There is a collections view within each library
@JuiceWSA might surely come a long and show you how he manages a ton of collections all within a single movie library (instead of separate libraries).
It’s not the same, but you can have the recently used playlists hub on your home screen, so if you create various playlists similar to your collections, you could quickly access like that.
