Feature Request: Object Refresh in World Editor

It would be great to have a right click on a model in the world editor's library -> mesh list to have it refresh all instances of the model in the world. Here is my current workflow:

1. Drop a model to the terrain. Ok needs a tweak, so make the change in XSI. Don't close te world editor.
2. Make change in XSI and export back to my game model folder overwriting my model's file.
3. Model in the world editor is invisible, so delete and go back to step 1.

Would be great not to have to delete the model in the event I had several located in the world.

Thanks for the consideration!
