Jonáš Hi! I set this up myself, let me tell you how it works for me.
I opened one account for all my regular costs. I calculated the amount that needs to be on that account (so all my regular costs), and set an automatic payment from my main account to my 'regular costs account' so I don't have to think about refilling the account. Before an automatic payment is executed, you have to accept this. When doing that, you can check your balance (but if you calculated everything correctly, you'll have enough funds at all times).
I think this is what you mean, right?
