Individual Filters For Y Axis Data Points

We should be able to apply different filters to different Y axis points in reports. At the very least for a combination chart.

For example, I have two lists. One list of our total market, the other is our customer list. I want to be able to apply the total market filter to the company count for one of my Y axis points. Then for the other one I want to be able to apply the customer filter.

This would give me a chart that shows our customers vs total market in one chart.
