Hierarchical (Sub) Accounts

Currently sub accounts are totally separate. What would be cool though is if there were hierarchical.

Master
- Sub Personal
- Sub Biz1
- Sub Biz2

So when I select Master I see all documents and receipts. When I select a subaccount i only see a filtered view.

Because at the end of the day I paid for all those things regardless in which sub account they are.

You could even allow nesting to sub-sub levels.

Permissions would be for a level so i can only see things in my level ie Sub Biz2
