SSRS charts : two series on the same chart

Hello,

I have very specific question about customizing charts using SSRS BIDS 2008.

Here is the problem: I have chart that shows series of different counted items per current and last 3 quarters. I need to add another bar to each series that would show average of count items for the same quarters. Essentially, I need to merge two different series on the same chart. I would prefer counts and average as bars on the chart and not as a running average line.

Is it possible to do it? How this can be achieved?

Thanks.
