This makes things a bit tough. One trick is to vertically partition the table into two new tables - with "From" in one and "To" in the other... then you can (horizontally) partition or cluster on each of these columns separately.
You can make it reasonably transparent by using a view to combine the columns again to get something that looks like the original table.
