Display certain totals as average values in Evdre

Hi,

we have a planning layout in which the columns contain forecast previous year (2008.TOTAL) ,actual previous year and 12 columns of budget for current year (2009.JAN, ..., 2009.DEC). The rows have sales quantity and a couple of unit rates (sales and COS).

We would like the system to display the unit rates as averages instead of adding them up, while the sales volume should be added up. Is this possible?

regards

Dries
