Extract Document Naming Convention from filename
When a Document Naming Convention is set up, Twin will try and match the filename to the Document Naming Convention during the upload progress. This will extract the document number and related metadata from the filename and fill in these fields on the upload screen. When a user formats the document filename according to the Document Naming Convention, this will result in less manual input during the upload process.
