how to config multiple steppers for one axis

Hi,
I googled around a bit and tried to search the forums with little found.

I'm setting up a gantry that has steppers on both sides.

My driver board has 4 drivers and the current single motor setup for this axis is something like:

# Y-Axis Pins
net ydir => parport.0.pin-03-out
net ystep => parport.0.pin-08-out

How do I tell it that:

1. ystep needs to go to two pins on the parallel port
2. ydir needs to go to two pins as well.

Regards,

net ydir => parport.0.pin-03-out
net ystep => parport.0.pin-08-out

easy to just duplicate add the second port as ..
net ydir => parport.0.pin-09-out
net ystep => parport.0.pin-10-out

After digging around more and reading the docs it turns out to be as easy as:

net ystep => parport.0.pin-08-out parport.0.pin-10-out

Note: pin numbers in above example are not actual pin numbers for any particular controller.)
