All access stash, you can stash something on one account and if u need it on another ( if u have a second account ) why not make a stash to where when u open it, you can enter in the email/password to ur other account and take stuff out of the stash from the account ur currently on? A lot more simple than maybe having someone transfer items with chances of getting scammed or using 2 devices. Just an idea I had, sorry if it's unclear but u get the idea
