List change sets that will be included in next baseline

I need to use the command line to get a list of the change sets completed since the last baseline for a management report to determine whether all the requested work is actually read for the next phase.  

I see I can use lscm list stream and lscm list baselines to find the last baseline but I can't figure out way to use lscm list changesets to find the changes since the last baseline (although I can list all the changes with lscm list changesets).
