Using generator to create concept instances

Dear sirs

Is there any way to create new instances of concepts, inside a solution, using the generator of one of the languages referenced in that solution?

Currently I'm using a MPS plugin to programmatically create new concept instances and it works fine

  Iterable<? extends SModule> smdAllL = ProjectManager.getInstance().getOpenedProjects().get(0).getModules();
  foreach modCurrentL in smdAllL {
    if (modCurrentL.getModuleName().equalsIgnoreCase("my module name")) {
      Iterable<SModel> mdlAllL = modCurrentL.getModels();
      foreach mdlCurrentL in mdlAllL {
        if (mdlCurrentL.getModelName().equalsIgnoreCase("my module name.my model name")) {
          mdlCurrentL.add root(new node<my concept>())

But I wonder if there is a better and more natural way, specifically through the use of the generator of a language that I refer to in the solution.

Many thanks
