As nobody else has replied yet, I’ve had a guess, but I don’t know whether it will help.
I haven’t got Battery, but I have used multiple tracks for other multi out VSTi’s. Is this what you want?
This is what I do:-
Right click in the Track Control Panel area and select the option called Insert virtual instrument on new track (see picture below).
Select your multi-channel VSTi.
You should get the option to Build Routing. The picture below is an example using Kontakt2
Select OK and you should get a track for each output.
