Can't save Level asset w/ project open on 2 locations

The project I am working on is being done on Multiple workstations.

When “Workstation B” has the project open, “Workstation A” can’t save the assets (Levels, objects, materials, ext…) So I am forced to Save and Close on each system if I want to save on another.

Is there really no way for people to work on the same Projects at once?
