Initializing Multiple 6555 Cards as a Single DI (C/C#)

Question

Hello, 
I am working on adapting an existing Test Executive Shell (writen in C#) onto an NI PXIe system. The current system I have uses 4 NI6555 cards, and will need to test boards with more than 24 pins. The original shell initializes all DI cards as a single DI with channels 0-96, instead of channels 0-24 on card 1, channels 0-24 on card 2, etc. For example, a test engineer could write a series of tests referencing pin #76 and the drivers would know that refers to channel #13 on the card in slot 8. 
Is there a way to initialize multiple cards at once to accomplish this, or some other simple solution? I am developing this in C# using the C to C# wrapper. 
Please let me know if I need to give any other info. Thanks!
Jason

Hey Sapan ... thanks for your reply ... we want to replace the values on input and we have combinations like:
A ... maps to 1
B,D ... maps to 2,4
A,C ... maps to 1,3
A,B,C,D ... maps to 1,2,3,4
D,B,C,A ... maps to 4,2,3,1
C,A,D ... maps to 3,1,4
etc
It looks to us like the only way to do it is to export all the content and then build the import value map for each variation manually. As there are 32 variations this is do-able, but not ideal. We had hoped that the import map process would see each individual value in the field as a unique item and therefore import with a very basic mapping.
Have you done anything like this before or do you think the manual approach we're taking is the best option here??
