Does anyone know a good third-party tool or extension that actually helps organize Amazon wishlists because the built-in system is honestly driving me crazy?

I'm trying to plan my sisters wedding shower list for October and I've ended up with like 300+ items spread across five different lists. Honestly the standard Amazon UI is just garbage for this kind of volume. Moving things between lists is a nightmare and the sorting options basically dont work half the time. I'm based in Seattle and I've got a bit of a budget for this if there's a paid app or something, maybe $10-20 just to save my sanity over the next few months. My use case is basically just sorting through hundreds of potential home decor and kitchen stuff without losing my mind.

I did some digging and found this thing called Wishy but it looks super old and I'm worried it might be some kind of scam or just totally broken now since it hasnt been updated. Then I saw people talking about Giftster but that seems more like a social network thing where you have to manually re-add every single link? I really need something that can just pull my existing data from my account and let me tag things or drag and drop them more easily.

Is there a better way to do this or am I just stuck clicking through a thousand pages on the mobile app? Its taking way too long to get this ready and the wedding is coming up fast...
