can the position of the crankshaft position sensor be changed easily in a PCM's programming?

example:

say you were going to do a PCM conversion similar to EFI connection's setups:

the trigger has to be aligned to TDC, and the PCM needs to know where the sensor is in relation to the crank, so say the sensor is on the opposite side of the block from the original application, could that be corrected without too much effort? maybe just changing a parameter in the .bin? or would you need to do an external trigger with the sensor in the correct position?
