Yes switching leads of only 1 lane is the solution.
It is the same as the riko 's digital solution for the arc pro as shown in top of slotforum scaly digital forum.
On the arc pro you finally get the lane design choices of the advanced but not the use of analog unless you want opposite drections like the one that you currently have problem with on the advanced.
But for digital only users of the arc pro it is godsent.
However when it is done to the advanced , you may fine the analog direction choice is opposite to the button selection, as in right goes left and left goes right BUT both lanes finally go in same direction and can be easily reversed.
Now consider the advanced to be the best scaly has produced, but sadly lacking wireless , the only true endearing feature of the arc.
As for why solution was not posted on slot forum, was unable to get back on there.
Did post it on slot car illustrated and asked several members of sf to post it but obviously they did not.
