This might be just me/an edge case, but here’s the scenario.
I have one account called “Payments” which I use for paying Direct Debits like PayPal or when I buy something online. In general all DDs that I want to manually assign to the actual account. I also use this Payments account for many outgoing payments. As a security measure, there is no money in it until I have to pay stuff.
So it’s basically my Proxy account.
When I want to make a transaction I sometimes realize only on the last screen of the wizard, that the balance is not sufficient. Of course I could use another account but that would break my system and defeat the purpose of the payments account.
So I would appreciate having some sort of “Move the money from a different account”-Button that moves the money needed for the transaction into the “Payments” account and enables me to pay with the account I want, rather than having to cancel the whole transaction, move the money and start the payment process again.
