Mapping ProChannel Parameter to ACT Midi Controller?

Is it possible to map the Pro Channel controls to a controller using ACT?  

You can't do this directly but you can assign a button to step back and forward through the Prochannel modules.
 
To do that...
 

1. In the ACT dialogue click on the "Options" tab.
2. In the "Buttons" assignment area, Select a bank & button, let's say Bank 1, B1
3. Assign that to "Focus Previous Plugin"
4. Then assign Bank 1, B2 to "Focus Next Plugin"
5. Save as a presest if you wish, overwrite existing, or just exit. The assignment will be saved either way.

 
Now when you have say the compressor in focus being controlled by your controller and you press B2, focus shifts to the EQ (or whatever is next in your chain) for control of that, press B1 and you're back at the compressor (or previous in your chain)
