I'm trying to create an index that will internally change back and forth between Ascending and Descending depending on the value of a field.

Let's say I have a table with the following fields and values.

cValue AorD
01 A
02 A
03 D
04 D
05 A
06 A
07 D
08 D

I want to index on cValue Descending but internally cValue would be subIndexed as either Ascending or Descending depending on the value of AorD so that the final index would produce the following result.

cValue AorD
01 A
02 A
04 D
03 D
05 A
06 A
08 D
07 D

Can anyone think of a way to do this even using UDFs if needed?
