Is there a way to show comments from tasks in a resolution? Our specific use case is:

We have a template that is used to report potential safety hazards. For the resolution we typically list resolution (obviously), actions taken to mitigate hazards or any repeat of incident, and employee retraining after incident completed by (name/date). I would like to create a new template that uses a workflow to turn the "mitigation" step as well as the "employee training" step in to assignable tasks. Upon task resolution the information would be added to the task comment section. 

Is this something anyone here is doing, or is there a better way to handle this?
