When viewing a PDF proposal or other PDF attachment submitted by a bidder in Building Connected Pro, it would be beneficial to have the ability to make and save markups, comments, annotations, etc. on the PDF file in the viewer within BCPro. Currently, you can only either download the subject PDF file or open it outside of the BCPro platform. When you open the file outside of the BCPro platform and mark it up, the changes don't get saved to the file saved within the platform (you are instead prompted to save the file locally).
