Canadian Proof Sets

I have a 1989 Canadian Proof set.  It consists of 7 coins as it has both the Loonie and a silver dollar.  I can't find it listed here.  Does Numista not list sets?  Or am I just not searching correctly?

Sets are a new addition to Numista. Yours may not be listed yet but you can certainly add it!

How would I add it?  I don't see a category for sets.  If you have any examples, I can go from there.

If you look at existing sets, you can scroll to the bottom and https://en.numista.com/catalogue/contributions/new_set.php?duplicate=3325
