It would be great to support per-person cash flow from end to end. Many people keep finances separate even after getting married and it would be great to be able to see where money was coming from and where it was going in the cash flow view and likewise prioritize cash flows based on person.

For example if I make 100k and my wife makes 200k and we both have our own IRAs / Investment Accounts / 401ks etc. it would be really great to see how the accounts would grow over time and model the potential impact of a separation etc. (not to be pessimistic).
