It would save time renaming pdfs outside of a session so that the next version can be added to a session. I would like a session to automatically add an extension with the next number to the file name the same as windows when adding files with the same name. Example abcd.pdf is in the session, when you want to add an updated file to the session, Bluebeam would automatically name it abcd[2].pdf, and if another was added then abcd[3].pdf. This would be helpful while doing reviews of files and new pdfs are added for backcheck.
