Do you have any plans to allow Perform to calculate a total at the end of an appraisal?

We've just started using the Perform app. To determine annual increases, it would be ideal to have the appraisal have a rating total at the end. I understand that you'd like the appraisal system to be very flexible, but having the option to have a total at the end of an appraisal would be ideal. This way, we can configure the increases based on a particular rate range.
