Can I transfer items from my Amazon.com cart to another country site?

So I am in a bit of a panic because I am moving from Seattle to London in literally three weeks for a new job and I have been building up this massive cart on Amazon.com for months. I have like 45 items in there right now - kitchen stuff, bedding, some specific electronics I need for the new flat. My logic was that I would just keep adding things as I thought of them and then just hit buy once I got my UK address sorted and had my feet on the ground. But I just logged into the .co.uk site to check something and my cart is completely empty over there.

I did some digging online and saw a few people on some old forums saying you can use the Move to Wishlist feature and then make the list public and search for it on the other country site. But then I saw a more recent post from like six months ago saying that wishlists are actually region-locked now? So if I make a list on the US site I might not even be able to see the UK versions of those products when I am logged into the UK store. It is so confusing and I really dont want to spend five hours manually searching for every single spatula and power adapter again especially since some brands might not even exist over there or they have different names.

I also looked into the Amazon Global shipping thing but the import fees to send all this from the US to the UK are just insane. It would basically double my budget and I am already stretched pretty thin with the deposit on the apartment and the flight. I just want a way to port my cart contents over to the UK site so I can see what is actually available locally and just buy it there without the shipping nightmare. Is there like a browser extension or some hidden setting I am missing? Or do I really have to do this all one by one from scratch? I am so worried I am gonna forget half the stuff I actually need if I have to restart the whole process...
