Sharing of Testcomplete Project suit file between Testers on the same drive

Hello,



How can two testers share a testcomplete Project suite file between each other( e.g like you can share a workbook in excel)?



Such that both can access the file at the same time and also update it accordingly.





The testcomplete project suite file is on a network drive, both of us have acess to the drive, but our testcomplete is installed locally on our individal systems.





Thanks
