Is it possible to have a combination graph chart with a stacked vertical br

I have the following XML data :

I have produced a report based on this data which uses a combination graph chart. The sales for the current year are shown as a vertical bar for each month while the previous year and previous year but one are shown as lines. The report produces the correct output but I would like to add an extra feature
so that the vertical bar for the current year is shown as a stacked vertical bar so that the sales from each region can be seen within the bar rather than the bar just showing total sales. Is this possible byt altering the chart options within the template builder or would it be necessary to write some XSL code to do this ?

Yes and no, here's an example of stacked bar and area graph.
chart:
