The innovation occurs, just outside of US for some reason.
When I was a student, in 2001, Poland, I had such functionality - I had separate sub-accounts, each one of them with a dedicated IBAN number, receiving funds.
My monthly allowance from the parents went to one account, my payments from clients (freelance programming) went to another one. From that I distributed the money into another account for holiday savings, and to a spending account with a dedicated and free wire transfer of $5/day for daily spending - the only one I attached a debit card to.
Once I got a browser in my phone, I think around 2004, in case of emergency (as in "standing in line at the store, and discovered I'm $2 short"), I could transfer the money between various accounts instantly.
Another cool thing was that since my father had an account in the same bank, I received all the wire transfers from him instantly. As in, I call him, ask him for extra $100 for something, he says "hold on", opens up bank account on his browser, sends the money, and I instantly get a text message that the funds are received, and I can politely say "thanks dad, I got it" before disconnecting :)
Using past tense, because that was all in 2001-2004. 16-18 years ago. Right now I think all the major banks offer that, so nobody considers it a big deal any more. Oh, and now we have instant inter-bank transfers, but they cost "a lot" - like a flat fee €1, so people usually send the regular free ones, which take <1 work day to get delivered (<3h if you send them between 7am and 5pm) - regardless of which bank you are using.
In the UK we actually have free instant inter-bank transfers. I send money using the app from one bank to the other bank and get the push notification from the second bank confirming I have recieved the money before the UI in the app from the first bank has even confirmed the money has sent.
