Present Validation Station - Default Values


while indexing the document, I first read the QR code and woul’d like to display the read values as default values in the Present Validation Station activity. So that the user only checks the QR code read and adds the field values from document not present in the QR code. How to do that?

Also, how can I implement document indexing into intelligent OCR / machine learning models next time the same type of document is being indexed?

All this without using Abbyy OCR.
