How to change Function Values for a Function

When a Function is added to the list of Functions, its name and Function Values can be modified.

How to change Function Values:

1. If the desired Function is not yet present in the list, add the Function to the list.
2. Find the column with the property you wish to change.
3. Change the value in the row of the function and the column of the property.

Note: When a Function has multiple Categories, some Function Values can also have different values per Category for the same Function.
