Sonar and ACT

Hi,
I am using a novation Zero SLML2 controller without using AUTOMAP (!!). So I defined and universal ACT-Controller in X3 and assigned the first 2 rows of the rotary knobs.
How can I add another line to add more controlers? Im my case the faders on the right side of the zeroslmk2?
 
I tried to add a second Universal ACT-Device using the same Midi-connectins like the first one. But The faders (2nd connection) cant be defined using ACT.
 
Thanks for an answer and Your help.
