Canada FBA Inventory - How to see what's in Canada

We have started sending in products to Canada, but the inventory is combined with products that are also available in the U.S. for FBA. Is there any way to tell which products are actually in Canada and which ones are available for shipping by Amazon (through the U.S)?

My understanding is that people in Canada will be much more likely to order products that are in Canada as they take a couple days instead of a couple weeks (from the U.S.). I could just look at the listing on Amazon.com, but everything shows as unavailable (because I'm in the U.S.).

It looks like there have been a few threads about this but no real answers. Anyone have an idea of how to see the Canada FBA inventory separately from the combined U.S. inventory?

Thank you
