You can do this relatively easily, even if you have "mirrored" gearboxes. We do by tweaking our chain wrap. On one side, the chain runs along the bottom of the output sprocket, while on the opposing side, the chain runs along the top of the output sprocket. Thus, with all 4 motors running forward, the wheels spin the same way.
Although, this probably won't help you, because if I'm not mistaken 226 uses a direct drive system to the tracks.
Perhaps you could simply put in an additional 1:1 gear reduction on one side to reverse the output spin? You would lose a little bit to energy loss, but it would allow you to spin all motors the same direction.
Some teams design different gearboxes for left/right where the motor orientation is different on each side, this fixes the forward/backward problem.
I've been playing around with some different designs this off season, although we'll probably stick with chain next year, I'm curious to know how other people solve this problem.
