HI guys!

So, i have a list of credit card IDs and their corresponding balance.

The card IDs are then linked to clients. (clients table & credit cards table)

The credit card provider allows us to download a CSV file with card ID and Balance.

I would like to be able to update the balance of the CCs and keep the (correct) link with the CC and client.

Is this possible?
