How to customize Risk Matrix.

Hi,

We are using RTC3.0 ifix1 with Formal Project Management process.

I have some questions about Risk Matrix.

1, Risk Matrix is 55 by default.
Is there a way to change it to 44 or 33 etc?

2,The colors are green, yellow and pink.
Is there a way to use other colors?

3, Horizontal axis and vertical axis are measured 20%, 40%, 60%, 80%, 100%.
Is there a way to change them like 1, 2, 3, 4, 5?

4, When High is selected in Precision, "H" is shown in the Matrix.
Likewise, when medium is selected , "M" is shown and when Low is selected , "L" is shown.

Is there a way to change those "H", "M" and "L" to other characters?

5, Exposure is automatically calculated.
Is there a way to display the calculated number in the matrix instead of "H", "M" and "L"?

6, Horizontal axis is Impact and vertical axis is Probability by default.
Is there a way to change those attributes to other attributes?
Or is there a way to change the label "Impact %" and "Probability %" to other words?
