tracking more than 1 Smart Zone tower in the same bank with a Pro 96
 

is it possible to track more than 1 Smart Zone tower of the same system
at the same time in 1 bank with a Pro 96? i heard it is if you put
conventional freqs between each towers freqs. i tried it and it didnt
work, it stuck on 1 control channel. the system i used was the MPSCS in
Michigan. am i doing it wrong? i want to do it from home only, not
mobile.

example:
channel 1: Tower 1 control channel primary
channel 2: Tower 1 control channel secondary
channel 3: any conventional freq, set to fm mode
channel 4: Tower 2 control channel primary
channel 5: Tower 2 control channel secondary
etc.
