Multiple Profiles per user

I have two separate budgets I keep track of. My personal budget vs my families household budget. It would be very useful to be able to switch to a personal profile (similar to how Netflix and Amazon user profile separation) with a different set of banks connected and different categories assigned. In my imagination this would be a totally new user with totally separate data but uses the same login and subscription status.

A bonus would be able to extend this capability to other’s in my household, allowing them to use the same 5 bank connection limit without having to pay a separate pro subscription fee with their own login.

I do understand that this is likely a very complicated undertaking with many edge cases touching all existing interactions and could impact user experience by increasing complexity for first time users if done wrong.
