Cash Control: can I easily update the cash budget with actual cash balances on my bank account

Summary:

The new (22C) feature to use a budgetary control validation in the payment process request is for my client a very useful feature, since they make large payment batches for many BU's at once. With this budgetary control they can determine which invoices can be paid (sufficient funds) and which should be removed before compelting the batch. Now completed batches have to be voided when later in the process there appears to be insufficient funds on one/multiple bank accounts.

I was able to complete the set-up and load a budget in spreadsheet, but then I ran into some operational questions, which could not be answered through the SR's I have already registered.
