It can do a multi-pv mode for engines that support it. Ruffian UCI can do it. Here is a sample output of the analysis of the opening position, with the top 5 moves according to Ruffian for depths 9, 10, and 11. The output is upside down (best move on bottom). Maybe you can use this to find the answer to your question.
