Listen for file changes in just a single project?

When I have code like:

MessageBusConnection connection = project.getMessageBus().connect();

connection.subscribe(VirtualFileManager.VFS_CHANGES, new BulkFileListener() {
  @Override
  public void after(@NotNull List<? extends VFileEvent> events) {
    for (VFileEvent event: events) {
      System.out.println("event = " + event);
    }
  }
});

I seem to be notified of all virtual filesystem events, not just the one specific for the project I specified.

Is there a way to subscribe to events only for files in a specific project?
