We can now process offline credit card transactions in webview batch which is great, but I'd also like to process credit card transactions through BBMS in batch at the same time, so a hybrid of online and offline processing within the same batch. However, when I enter the transaction as credit card, there is no requirement to choose whether you would like to process it with BBMS or offline, so if we hadn't taken the payment offline, we could easily skip that step and enter gifts via batch that had never been processed.

Could there be a choice pop up or drop down column that is fed by choosing credit card as the payment type that asks you to confirm whether it was taken offline or is to be process via batch?

I think without that it would be impossible to move to processing credit cards via batch until I can guarantee that taking a payment won't be skipped.
