Updating Budgeted Units with Physical % Complete

I am trying to update an engineering schedule which is basically just a drawing list. I am using Primavera 5.0 and would like to know if I can update budgeted units by updating the physical percent complete for the activity.

My purpose for wanting to do this is to make a simple planned curve vs. actual curve and calulate an overall percent complete for engineering.

Or is there some other way to do this. From what I understand P3 is able to easily do this.

Thanks
