I'm just trying to confirm what I've come across by searching as sometimes people think a thing is impossible but it's really not. You can't take a written book item and jet the raw json out of it? There's always data lost when using json to generate a book? So there's no possible way to say, copy a book text including hex colors, urls etc into an unwritten book for the purpose of updating it? I find this absolutely wild, can someone confirm or deny?
