Sorry I am just seeing this now - Hopefully you've got it sorted out by now - but in case you haven't, you can assign a button on your ACT controller to "Next Track Bank" and "Previous Track Bank" which should move the WAI in banks of 8. Do this on the "Options" tab of the "Controller/Surface Properties" page, for the buttons you have mapped for this purpose on the "Controllers" tab. I have my Oxygen 61 keyboard set up so that the faders (track volume) and rotaries (track pan) move in banks via two bank select buttons on my keyboard.
