Masked supplier bank accounts in Internal Supplier Profile Change Notifications

Summary:

We have switched on bank account masking as we are running Expenses. However this means that bank accounts are masked everywhere, so when a supplier bank account is added or updated, half the bank account is masked in the notification to the approver. This is not acceptable to my client, they are saying how can they approve a bank account when half of it is masked which is a fair point.

I am wondering what workarounds people have implemented to get around this? We cannot switch the masking off due to Expenses being live, so find ourselves in impasse. Only the last 4 digits of the bank accounts are visible in Notification so how can the approver be confident that the first 4 digits are correct?
