Adding to the above discussion is it really possible to scramble the words that we actually receive from the automated generator? I don’t know depth of it, but when we generate any address the phrases are already associated with it and there is no way we can change it. I am saying the first time change when we generate it. Let us say I have newly generated address and creating a wallet with Back up keys. Wallet has given 12 words but I want to change them right away manually, why isn’t that possible?

Is it possibly because someone might overlap with my words and sequence? (Though this may not happen considering the 12 words and their numerous combinations. But just curious about the technical explanation behind this.
