Multi-user use of Sailwave

Currently fine tuning setup for a worlds, we have several machnes and have a network and would like to use one central copy of Sailwave.

I understand that Sailwave is a single user system, but is it possible to set it up so that when user b opens it while user a has it open, a message comes up say that it's in use?

Currently in 2.02b1, it will open for both users and both can save it, but neither can see the changs made by the other.

Your prompt response would be appreciated.

cheers
