"ROC circuit" discussion

[PauweBaggio]

Hello there,
I am using BTB from long time, and I did several circuits in the past years.
Now, I would like to make a "ROC circuit", basically a track which 2 different path, like Wembley Stadium etc...
I don't know if is possible with BTB or not, anyone else already tried to make it, and can give me some advice?
thanks!
