Show process time at activity level for previous versions

We would like to be able to see process time savings at the activity level. Currently, in the Change Log, viewing a previous version and running the Process Time Saving Report only show the process total time for previous versions. If the data is saved at the activity level to begin with, we should be able to see that in the procedure when we open the previous version. Our current work around will need require saving the Process Time separately for better analysis.
