In other words you want to be able to program selectively the matrix metering points, not to have "multiple spot metering"
I think this would be a nightmare, since matrix metering is set up to consider typical shooting modes, and evaluate them based on some rather nebulous concept of scene composition.
I think the best you could hope for is to somehow modify the metering by selecting a "key point" of the scene based upon the AF point used. To me this would be logical because the AF point is normally also where you want exposure to be perfect.
To have a fully programmable matrix metering, I think it would be too difficult and time consuming to set for each different scene, and after all, that is why you are a photographer, it is up to you to check exposure on each scene, if it is that radical, by using spot metering and make the decision yourself.
I don't think the camera has the capacity to understand how you want to shoot every scene. Until someone develops a
Mindread.exe function for the camera, I believe this is something best left to the photographer.
