Sparse rendering

Is the Sparse function working? If set in Scene Manager, it seems to have no impact on Max, and does not change the render sequence in Render Manager. Also cannot find the Sparse setting in the Render Manager screens as suggested in the documentation. Maybe I am missing something?
Edit: I see that sparse works if a job is submitted from inside the Render Manager program, but it does not seem to be responding that way from a job submitted by Scene Manager through the Max job submit button.

The sparse setting set in the Scene Manager should only take effect in the Render Manager when you are using the Scene Manager Scene option. In any other case, rendering locally, batch rendering with Scene Manager or using one of the quick submit buttons in max the sparse option won’t take effect.
