I would like to be able to recognize updates when I am uploading requirements. So when I have uploaded for instance 10 requirements to Practitest by using a 1.0 version of an excel, and I update the document and do a re-upload of for instance a 1.1 version. I would want Practitest to recognize existing requirements and identify changed and new requirements. This would enable me to see what testcases are affected (and should be modified/ deleted) and what requirements need new testcases.
