OD Cost Matrix for symmetric distances

Hello all,

For research purposes, I am currently solving OD Cost Matrix to compute shortest paths distances for about 10'000 origins and destinations (origins = destinations). I am using a undirected network, so the distance from A to B equal distance from B to A (symmetric distances). Therefore, do anyone has an idea on how to customize the OD Cost Matrix tool so that it only computes A to B and not B to A ? This would halve the size of the database and the computing time.

Any idea ?
Best regards,
