Feature Request: Group people together for reimbursements

[TimonTrukker]

If I go on a group trip, it would be nice if i could group my family together for the reimbursements. For entering expenses, everyone is listed separately, which is easy to divide expenses. But on the balance page, I don't want me, my wife and my kids to be a separate entry.

All of our expenses/payments/debts can be thrown on a pile and settled together.
