Behringer XTouch Extender Questions

New

Hi, I just got my XTouch Extender hooked up to my DAW (Reaper).  I'm using the XTouch as my primary controller, and the Extender should be just that - an extender.  Currently the scribble strips want me to use the XTouch for channels 1-8 and the Extender for 9 - 16.  I want that reversed.  I want the channels to read through the Extender first.  1 - 8 should start on the Extender and 9 - 16 should be through the XTouch.  Is there any way to do that?


 


Also, how do I color code the scribble strips?


 


Thanks in advance!
