I'm not a creator so I don't have the knowledge about this, but I know there are 2, 3 and even 4 track tracks available. These are done as 'bridges' even though they are track. Perhaps you could look at their config.txt files and it might give you some pointers? If I can find them I'll post the kuids for you.
Cyberstorm also has some invisible track four track stuff on the DLS, you could also have a look at their config.txt files...
