Allow extracting transaction date from unstructured remittance information

My bank’s integration is messed up for some reason (probably the bank’s fault 😅), and both the booking and value date are the same. The actual correct date which I want to use is the booking date as you mention, but this is only available in the unstructured remittance information, and this is the same for the merchant name.

The merchant name is possible to get from the unstructured remittance information using Eta templates and I just got it to work really reliably with some ChatGPT'ing. The correct booking date would not be possible to use for now, even if you switch my account, as the data provided is wrong. Here are some screenshots.
