Multi-user access control

User #1 opens a PDF on a server and starts making changes.  User #2 opens the same file and starts making changes.  User #2 for example can create sticky notes and make lots of comments.  When User #2 tries to save his changes he's denied as User #1 opened the file first.  Is there a way (like with MS office) that User #2 will be warned when opening the file that his version is read-only?

Thanks!
