I may have answered my own ??.
To switch track inputs, open Options> Prefs> Audio> Driver
Highlight the ASIO pair you want to record.
That pair is the input pair on the track you're recording.
To record from a different ASIO pair, go back to Driver settings and highlight the pair you want to record. Rinse and repeat as needed.

There is not an option to configure
ASIO 0/1 >> Track 1
ASIO 2/3 >> Track 2

You cannot record multiple tracks from different ASIO inputs simultaneously, correct?
