PDM Proffesional, IEdmHistory2 rollback Comment

When doing a rollback to a line item in the history, there is no way to insert a comment and it doesn't leave a visible sign of the rollback in the history dialog.  Has anyone experienced this or have a workaround.

I need to rollback to a history line vs just a version, because the files have a Revision at  released state and transition to WIP in the same version.

Thanks
