Is there some sort of wishlist script?

I didn't post it under suggestions because that's something I think can be easily handled by a script; these days I pretty much only use the wishlist tab, which is very handy, but has a limitation of Steam wishlist not allowing packs. That means if, say, a game has an edition with bundled soundtrack, I'm probably gonna miss a giveaway for it.

Is there a script that shows you only things you wishlisted + packs containing that? One handy feature would be an option of omitting packs that contain at least one thing you already own.
