Well I decided to call support around midnight (I guess that would be yesterday) by now. And lo and behold I got a hold of someone and they were able to map her account in for the powerwalls. So yay my wife has access to all our Tesla products from her own account.
Apropos to the original post, it wasn't a powerwall but solar panels, we purchased a property with Tesla solar. Once that transfer was done I contacted support (I think I had to prod them) and I got the account to show up on my account. I am certain I had contact support to clean up minor things like the names on system. Initially I had access but it had the previous name went to manage the specific product.
