Ability to map "stacked" lane guidance.

A stacked lane is one where you have one lane turning into two. An example I have is here in Calgary AB Canada, we have a rail underpass that you make a right turn onto, but there is a median between the two lanes (its a one-way) and you need to be is the farthest lane access the left turn at the other side of the rail underpass.

And right now, we don't have the ability to show that the first right lane is "stacked lanes"
