More than one freqency response in Sisotool

Hi. I have to create a controller, that is clinged to two other frequency responses. Is it possible to show more than one frequency response in Sisotool? Something like bode(A,B,C) and only B will be edited.

Starting with R2010b, you can evaluate controller against multiple plant models in sisotool:

>>s=tf('s');

>>G=stack(1,1/(s+1),1/(s+2),1/(s+3))

>>sisotool(G)

Observe 3 curves representing 3 different transfer functions in the bode plot. See this demo for more details: http://www.mathworks.com/products/demos/control/CST_multimodel/
