When you upload a document for the first time, you have the option to enter a URL from which a proof will be generated. ProofHQ captures that URL and generates a proof that can be commented on in the tool. If you want to add a new version of the proof (after updates have been made) you only have the option of using the same URL that you used to create the first document/proof or uploading a document from your computer.
There are scenarios that I need to use a different URL for the new versions. A third party tool we use creates an unique URL each time you make an edit to the program and publish it for viewing. I would like to add a feature that allows you to enter a different URL for each subsequent version.
