You should automate that. It is already to a large extent but
if it isn't, or if your unhappy with some of the choices, you
can set that up yourself. But after it's setup, it does it
for you. You can change it ...

Uhm, what is 'balance-mode' BTW? It's not
installed/available, either.

It sure isn't this [1] (and both links are broken) because
I don't deal with credit cards.

Maybe that was something I did I don't remember.
I don't remember.

Anyway to the OP you see how it works, right?
Pretty straightforward. Like C++. LOL
