<prompt> Human: This is what Id like to do:Say I have four bank accounts, A B C and D. My biweekly paycheck is direct deposited into A, which is the account I use to pay bills. Id like to keep 4000 in there at all times. B is another account, say for travel expenses, Id like to keep 2000 in there, and 500 in a third account C. D is my savings account.So if the day before pay day, I have 3900 in A, 1800 in B, and 450 in C, Id really like to find a system or process to automatically make transfers such on pay day money is deposited into A until A is at the limit I have set 4k, then on to B, then on to C, and put whatever is left over into D.Does that make sense? Does such a bank or service exist anywhere? It would make budgeting really simple for me.Thanks for your time.  <response>: if you dont need them to be hard limits to the amounts in each, and are just using them for budgeting purposes, look into one of the many banks that offer virtual wallet type services.from what I know, you have one account, but can self-define different sub-accounts under that account. The money is really in the same account, but it can be tracked in any number of virtual sub-accounts for whatever reasons. You can easily move money back and forth between each sub-account, as well.
