using CVS with QNX Momentics in 6.3

Hi, I am using Momentics and CVS server (windows box). Everything works ok when commiting and updating and synchronizing to check conflicts etc… but how can we setup CVS or Momentics so that they can be notified if two different users checks out the same project from the CVS server. It seems like from momentics point of view, who ever commits the project last has to deal with conflicts… but if two developers knew that they where working on the same project, maybe one can work on another project. Any suggestions?
